The Roller Vane Pump, also known as ‘Allman Pump’ is an extremely versatile and low-cost system. It can be used for many different applications, but worldwide it is primarily used for agricultural spraying.
It can be operated from the Power Take Off (PTO) on a tractor at 540 RPM by means of a special quick release coupler. They can also be connected independently via a standalone Motor.
Our RVC25 Allman Pump is made from a solid cast iron material, offering robust strength whilst also being self lubricating. The rollers are coated in an Acetal resin which will withstand most herbicides, insecticides, fungicides, pesticides and liquid fertilizers.
