pumping system: vacu-storm


The VACU-STORM system combines the advantages of a vacuum pump on the suction side and a STORM centrifugal pump on the discharge side. It is an ideal solution for users who are looking for an absolute flexibility. This process guarantees a high performance. The pumps are P.T.O. driven via a reinforced one-piece gearbox. The Jurop PN 130 - 13,000 l/min is integrated in the drawbar and is used for suction. The PN 155 and PNR 155 (+/- 15,200 l/min) are available as options. The vacuum system has the great advantage of being well adapted to all pumping situations (underground or off-ground pits, funnel, etc.). The STORM centrifugal pump (10,000 l/min) is designed to feed the rear implement. It allows spreading over large widths and with a high and constant flow rate. Ideally placed under the tank with the stone trap, it ensures a smooth and even feeding of the slurry, while reducing maintenance to a minimum. This design provides a safe and convenient access.

JOSKIN mainly installs mobile vane pumps driven by an eccentric rotor that always rotates in the same direction: the air flow is directed by a deflector valve to either pump or spread slurry. They all achieve an equivalent vacuum, regardless of the model or capacity. It is therefore the air transfer capacity of the pump that should be taken into account. JOSKIN offers a range from 4,000 to 15,500 l/min. The main models are the MEC from Battioni & Pagani and the PN(E/R) from JUROP. They all have at least one forced drip lubrication that can be adjusted manually or automatically at the factory. The lubrication takes place both during the suction and the discharge phase. The JOSKIN Vacuumoil is specially designed for the pump vanes: a 5 l can is supplied with each slurry tanker equipped with a vacuum pump with vanes.

All JOSKIN tankers with a vacuum pump are fitted with a tank overpressure security set at + 1 bar. When the pressure inside the tank exceeds this value, the springs compress, the top lid of the valve lifts and the pressure drops rapidly. Once the pressure is reduced to below + 1 bar, the lid returns to its initial position thanks to the return springs.

Based on a float system, the ball safety device (or overflow valve) prevents the slurry from following the same path as the air. When the tank is filled, the ball blocks the air outlet and prevents the slurry from flowing into the pump.

Cooling the pump is a major challenge for manufacturers. In addition to a traditional air flow, pumps are designed with fins for a conductive cooling. There is a slightly more efficient system, called "Ballast Port", which is also a low-cost solution: a continuous injection of fresh air into the pump body cools it down and allows it to work at 60% vacuum continuously. It is used on most of the models manufactured by “JUROP”.

The self-cleaning syphon (30 or 60 l) serves as an additional safety device between the tank and the pump. It is designed to empty automatically when air is forced back into the tank. For an easy maintenance, self-cleaning syphons are fitted with a cleaning plug.

This ecological and economical system offers 3 advantages: it collects the used oil coming out of the pump, reduces the noise pollution considerably and sucks in the air from above to prevent it from becoming dusty. This accessory considerably increases the lifespan of the pump.

The STORM system propels the slurry out of the pump by the centrifugal force created by the rotation of a screw around an eccentric pump body. The highest flow rates are achieved with this pumping mode. STORM pumps only work on the discharge side.At 750 rpm, a flow rate of 6,000 l is achieved, while at 1,000 rpm, it rises to 11,000 l. The pump is equipped with a stone trap and is driven by a universal joint shaft on the tractor power take-off.A3-way valve can be fitted at the front of the tank to mix the contents in a closed circuit.
