Flux Pumps - F/FP 425 Drum Pump

Flux Pumps - F/FP 425 Drum Pump

Features & Specifications:

With the F/FP 425 there is less then 0.05 l residual amount left in a 200 l drum. The integrated backflow valve prevents back flow of the medium into the emptied drum. The minimum residual amounts in the drum reduce additional cost for cleaning the drum and waste disposal. The pump is ideal for transferring various low-viscosity - also aggressive - media and is suitable for emptying drums and IBCs. It is driven by a commutator motor, compressed-air motor or brushless motor. The outer tube is available in stainless steel, hastelloy C and polypropylene.
