Principle

Vacuum Pumping System
The vacuum system creates an atmospheric pressure difference in order to fill or empty the tanker. By creating a vacuum (depression) in the tank, slurry can be sucked. When spreading, the principle is reverse: the tank is pressurized by the pump, which allows to expel the slurry.

Which pump capacity?

An appropriate capacity is used to create the vacuum before starting to fill the tank or to pressurize it during the spreading phase. The pump then "merely" has to keep this vacuum or pressure.
Choosing a too big pump means wasting the tractor traction power, with a risk of premature wear. The effective vacuum rate is always the same, whatever the chosen type of pump may be.
Once the capacity of the pump is selected, it is possible to choose a given type of greasing and cooling system.

Direct connection or speed-increasing gearbox?

The 1,000 rpm version is also more interesting because, in combination with the tractor P.T.O. rpm selector, it allows to adjust the pump capacity to the required spreading flow. Furthermore, the pump that is driven at a lower rpm will spare the engine, which is therefore beneficial to the traction capacity of the whole carriage.

Cooling

Next to the air flow through the pump, most vacuum pumps are also fitted with vanes acting as a conduction cooling system. However, for a more efficient cooling, it is possible to choose the "Ballast Port" system, which is a low-cost solution.

This system is used to cool the pump by injecting fresh air in its housing and to constantly work at 60% vacuum. It is mounted on the PNR 155.

Vacuum pumps WITHOUT lubrication

Vane

• Pump system with mobile vanes
• Driven by eccentric rotor
• Deflecting valve to direct the air flow in order to suck or spread.
• Necessary and forced lubrication (drop by drop) on every pymp delivered by JOSKIN

Vane
Vacuum pumps WITHOUT lubrication

JOSKIN mainly installs pumps with mobile vanes driven by an eccentric rotor that always turns in the same direction: the air flow is directed by a deflecting valve in order to spread or suck slurry.

All normal vacuum pumps create the same ''vacuum''; only the air flow capacity of the pump matters.

The range of vacuum pumps with vanes proposed by JOSKIN goes from 4,000 to 15,500 l/min. The main models are Battioni & Pagani MEC and JUROP PN and PNR.

All vane pumps delivered by JOSKIN are at least fitted with a forced lubrication system (drop by drop), which greases the pump both during the suction and spreading phase.

Vacuumoil

The JOSKIN Vacuumoil was especially developed to lubricate the pump vanes. A can is provided with each delivered vehicle.

Vacuum pumps WITHOUT lubrication

Lobe rotors

Lobe rotors

• Vacuum model with high capacity
• Two volumetric rotors with lobes instead of vanes
• Depression in the tank through the rotation of the lobes
• No lubrication since there is no contact between the mobile parts
• No wear nor polluant emissions

The Jurop DL pumps are vacuum models with high capacity (from 14,750 to 20,850 l air/min) that are especially used in the industrial sector, and particularly on hydrocleaners.

They work with two "volumetric" lobe rotors instead of vanes. The rotation then creates a depression inside the tank, which allows to suck slurry.

As there is no contact between the moving parts, the pump can work without being lubricated. It is cooled by air injection.

The advantage of this type of pump is the high capacity and the limited dimensions. Moreover, the Jurop DL is not subject to wear or pollutant emissions.

It is standard fitted with silencers on the filling and exhaust pipe.

Three models are available: Jurop DL 180 (17,600 l air/min), Jurop DL 220 (21,600 l air/min) and Jurop DL 250 (25,000 l air/min).

JOSKIN fits its DL pumps with a temperature alarm and filters, whose advantage is to suck so much purified air as possible in order to avoid foreign bodies.

Accessories for vacuum pump

Protected pump

The pump is protected against the well-known "slurry-hammer" (slurry flowing into the pump) thanks to an anti-spill valve combined to a self-cleaning syphon. The compression circuit also includes two safety valves: one on the pump, one on the tank. Since the pump is the heart of your spreader, it is worth this attention.

Tank pressure relief valve

Tank pressure relief valve

All JOSKIN tankers with a vacuum pump are fitted with a tank overpressure security.

Ball security (anti-spill valve)

Based on a float system, the ball security prevents slurry from flowing in the same pipe as the air. Once the tank is full, the ball blocks the tube.

Ball security (anti-spill valve)
Self-cleaning syphon

Self-cleaning syphon

The syphon (of 30 or 60 l according to the pump capacity) is an extra safety between the tank and the pump. The inner pipe is designed in such a way that the syphon empties automatically when the air is expelled.

Ecopump

This ecological and economical system allows to collect used oils coming out of the pump, to highly reduce the noise level of the pump and to suck at the top of the tank in order to avoid dust in the slurry and to increase the lifespan of the pump.

Ecopump
Eco-purifier

Eco-purifier

Available with a capacity of 30 or 60 l, the Eco-Purifier is a combination of an Ecopump and a syphon but it keeps both their properties and advantages. It ensures a significant space-saving.

Pressure relief valve (Ø 150 mm)

The high-capacity pressure relief valve (Ø 150 mm) allows to quickly evacuate the air and prevent the pump from prematurely overheating. Thanks to this option, it is also possible to adjust the spreading flow by acting on the pressure in the tank.

Pump change-over

Pump change-over

Tankers with a vacuum pump are fitted with a mechanical pump change-over. A hydraulic control is available depending on the models. It is an essential option to use a filling device like an arm, a dorsal boom, etc. The change of pump can be done without leaving the tractor in order to anticipate the filling or spreading phase.

Pneumatic counter

By means of a membrane that adds each depression in the tank, the pneumatic counter, which is mounted on the syphon, accounts for the number of spread tankers.

Pneumatic counter

Mixing slurry in the tank

Hydraulic mixer

Hydraulic mixer

This device is a true mixer. It can be used both during transport and spreading. The built-in hydraulic motor drives vanes of 60 mm for a working diameter of 480 mm on an axis that rests on its whole length on an ertalon bearing.

Air mixer

This device, which can only be used when spreading, injects air at the bottom of the tank through a pipe. with holes over its whole length. Each of them is protected by a rubber piece in order to prevent slurry to flow into them.

Volumetric spiral pump
Volumetric spiral pump

1 - Rotor
2 - Rubber stator

Advantages

• Higher speed when filling/emptying (according to pump flow)
• Possibility to suck thicker slurry than with VACUUM pumps
• Compatibility with very long pipes (filling or spreading implement)
• Possibility to pump up to 3.5 m deep
• Standard equipment for mixing and transfer from pit to pit
• Pressure at the exit above 1 bar for a good distribution on high working width

General points

The spiral pump system makes use of a rotor with screw to suck and spread slurry. The rotation of the screw inside the stator then creates a series of hermetic chambers that move along the suction/discharge axis, resulting into suction and discharge.

The advantage of the spiral pumps is that they only suck until the liquid reaches them (and not like vacuum models until it reaches the upper part of the tank). They then send it to the tank or spreading implement. Sucking and discharging thick slurry through long suction pipes becomes then possible. Storage lagoons of more than 3.50 m deep can be emptied within a reasonable time. A 3-way valve makes it possible to apply, besides the filling and emptying functions, the mixing in closed circuit and the transfer from one pit to another one.

All spiral pumps on JOSKIN vehicles are mounted in an ergonomic and compact way, at the lowest point of the machine, in order to make maintenance and access to it easy. They are always lying in the liquid to be transfered; the risk of cavitation is thus significantly reduced.

• Compatibility with very long pipes (filling or spreading implement)

• Standard equipment for mixing
• Perfectly linear flow
• Pressure at the exit above 1 bar for a good distribution on high working width

General points

This system makes use of two rotors with lobes. As they turn, they create a vacuum on the suction side, which is determined by the rotation direction, which allows to attract the slurry into the pump housing. Then, the slurry is driven by the lobes, goes along the rotor wall and is spread.

These pumps do not take much place although they have a relatively high capacity. Their sucking principle ensures them a maximum stability and eliminates almost all vibrations. Furthermore, they are all standard fitted with an automatic stop system and wear rings.

Strengths

All VOGELSANG lobe pumps proposed by JOSKIN are also fitted with HiFlo® lobes ensuring a perfectly linear flow. In this way, they do not undergo vibrations and increase the lifespan of the drives and couplings. This unique geometry limits cavitation and allows higher rotation speeds, and therefore higher flows for the same pump size. Turbulences at the inlet are significantly reduced, just like wear to the lobes.

Vogelsang's particularity

Vogelsang pumps are fitted with a very efficient and dynamic injection system allowing to directly inject the foreign bodies into the pump housing, in order to avoid repeated shocks with the most sensitive parts of the lobes. The watertightness of the pump is in this way further improved.

Borger's particularity

Radial housing protection plates

Borger's particularity

All Börger pumps proposed by JOSKIN are fitted with the MIP technology (Maintenance in Place), which allows to immediately maintain and replace any parts in direct contact with the liquid. These operations can be carried out thanks to the pump wall with quick closing system providing an access to the inner side of the pump without having to demount the pipes and the driving system. Maintenance becomes then very easy and comfortable. Furthermore, JOSKIN standard adds radial housing protections to these pomps, as advised by the manufacturer Börger.

An appropriate position of the pump

Central location of the pump (Volumetra)

On the VOLUMETRA model, the lobe pump is located inside the drawbar. It will still be possible to reach it at the back of the drawbar for an easy maintenance.

Garda/Julia system

Advantages

• Emptying through spreading gun to spread on very uneven grounds while the tanker remains on a flat area.
• Irrigation works possible

The GARDA/JULIA system with 100% mechanical drive combines a Garda or Julia centrifugal pump with a vacuum pump (respectively Battioni & Pagani or Jurop). A pump change-over allows to choose the desired pump type. Standard delivered with a high-flow spreading gun, it is however still possible to feed a rear spreading implement or an umbilical system.

Garda particularity

Garda particularity

The GARDA assembly is the combination of two pumps:
• a MEC vacuum pump to fill the tank and spread traditionally;
• a GARDA centrifugal pump to make the slurry flow towards the spreading gun with a pressure that can almost reach 6 bar.

It is also used a lot for irrigation works.

Gun spreading

Spreading through a gun allows to avoid tracks on the arable land by directing the slurry towards the hillsides, which can even be reached above hedges from the road.

Mixing in closed circuit

Volumetric mixing through return to tank by hydraulic 3-way valve

Mixing in closed circuit

As an option on all GARDA assemblies, it is possible to mix slurry in closed circuit, which turns out to be very useful in case of quite thick slurry: this process takes place by setting slurry in motion.

Julia particularity

The JULIA assembly is the combination of two pumps:
• a PN(R) or DL vacuum pump;
• a Julia centrifugal pump of 5,000, 7,000 or 8,000 l/min.
This combination allows, through 3-way valves, to use wider implements or an umbilical system.

Storm emptying centrifugal pump

The STORM system sends the slurry out of the pump thanks to the centrifugal power created by the rotation of a screw around an eccentric pump housing. The centrifugal pumping system certainly reaches the highest flows (up to 10,000 l/min).
Storm pumps only work when emptying. The tank is therefore filled by the gravitational force through an upper hydraulic access. At 750 rpm, a drive flow of 6,000 l is reached. It is the case on Modulo2 tankers.

While at 1,000 rpm, the flow reaches 11,000 l, which is recommended on VOLUMETRA, Quadra, Euroliner and Q-Bigliner.

The pump is mechanically driven, with direct connection to the tractor, and is standard fitted with a stone trap. As an option, it is possible to mount a 3-way valve at the front of the tank to mix the contents in closed circuit.

Dual-Storm with mechanical drive

Dual-Storm centrifugal pumps

The Dual Storm concept is based on the combination of two centrifugal pumps: one mounted at the drawbar end to fill the tank and the other at the front of the tank to spread. It essentially distinguishes itself by its high flow, around 9000 or 10,000 l/min, according to the kind of slurry. Its three-blade propeller requires very little maintenance in comparison with the other high-flow volumetric pumps (with lobes or spiral), as it is less sensitive to the passage of foreign bodies.

Like all volumetric systems, the centrifugal pump allows a better filling of the tank while avoiding foaming (the foam being rejected into the pit by the overflow pipe).

The Dual-Storm system can be fitted with a mechanical or hydraulic (Power-Pack) drive with flow meter.

The Power-Pack ensures a high ease of use and a power suiting the desired flow. This device is not self-priming; that is why it is necessary to use a small vacuum pump to create a vacuum in the dorsal boom.

Power pack STORM : hydraulic drive

Both pumps are hydraulically driven by "Power-Pack", a hydraulic installation (160L/min at 280 bar) to feed the two hydraulic motors.
A Ramus valve isolates the tank and the case of the centrifugal pump. En standard, le DPA prend en charge la gestion de la vitesse de rotation de la pompe Storm.

The STORM pump is PTO driven while the Vacuum pump (PN 130/150 or PNR 155) is direct through the tractor's hydraulics. It's a simple assembly , but it requires a high flow from the tractor (+/- 85 l).
The system Power Pack is also available.

VACU-STORM with mechanical box drive

The Vacu-Storm pumping system includes the advantages of the Vacuum system in filling phase and the centrifugal one during the emptying phase. An optimal solution for the users looking for an absolute flexibility.

The VACUUM pump (Jurop PN 130), integrated to the drawbar, is used for suction. A PN 155 (ref 5352) and a PNR 155 (ref 2289) can be taken as options.

The Vacuum system has the advantage to be suitable to the the filling situation (pit, tower, funnel,...).

This pump is mechanically PTO driven through a reinforced gearbox.
The turbo filler option can be taken to optimize the filling phase.

The STORM pump (10.000 l/min) is used to feed a rear implement. It allows to spread on wide width, with a high and constant flow. It ensures an efficient spreading allowing to feed wide rear implements.

The centrifugal pump and the stone trap, fitted under the tank, grant a fluid and homogenous feeding and requires a minimal maintenance. This concept allows a safe and practical access.
