As an option, you can add one or more flanges of Ø 6" (150 mm), 8" (200 mm) or 10" (250 mm) to your tanker, or increase the diameter of the standard flange. These flanges give you an extra access to the tank and are often used for individual solutions.

JOSKIN uses four types of manual valves with quick coupling (with York valve) that differ in their diameter (6" or 8"), their type of jaw ("Perrot" or "Italy/Baroni") or their type of coupling for the suction pipe ("rocking" or "sliding"). The angled opening of the rocking jaw allows to easily place the hose in the coupling. The stronger mechanical design of the sliding jaw pushes the pipe flat against the neck, ensuring a better alignment of the coupling. All our manual valves are equipped with an air intake (York valve) as standard, which prevents the risk of slurry splashing when the suction hose is removed.

JOSKIN uses two types of couplings: “Italy/Baroni” and “Perrot”. The former is relatively light, but its domed head can cope with imperfect alignments. As standard, we offer the Perrot, as it is more robust, but it requires the two sections to be connected to be aligned.

JOSKIN offers a wide range of flexible hoses and galvanised rigid pipes (straight or bent) to connect your slurry tanker to your pit. In order to guarantee an efficient pumping work, it is important to keep the distance between the slurry tanker and the pit as short as possible: this is the only way to ensure that pressure losses due to the friction of the sucked liquid against the inner wall of the suction pipe are kept to a minimum. Which suction pipe diameter to choose? 6’’ (150 mm), 8’’ (200 mm) or 10’’ (250 mm)? Answer: focus on fluidity! The diameter of the pipes, openings and valves influences the pumping ease and speed. Taking into account, for example, a pressure loss of 15 mm (material "at rest" along the walls of the pipe), the useful passage of the 8” pipe is twice as large as that of the 6", and for a 10” pipe, 1.6 times larger than for an 8". Sucking a "thicker" slurry will be much easier with pipes with a large diameter. 6" is the most common type, the most economical and the easiest to handle. The 8" allows the flow rate to be increased, even at lower vacuum levels. Finally, the 10" allows very high flow rates. It is only available for high-capacity tankers with powerful pumps. However, one must be careful: a larger diameter also means heavier suction hoses, hence the interest in large diameter filling arms.
