Gear flange pumps

Gear-flange pumps are pump heads with a free shaft end, also known as flange pumps. They are used when a motor, gearbox, or drive is already in place, or when the pump is to be integrated into a machine. Linn-Pumpen manufactures the F and D series for this purpose, made of gray cast iron with gears made of case-hardened steel.

The selection is based on the fluid, viscosity, flow rate, pressure, temperature, seal, and installation configuration. Both are based on the F pump model made of gray cast iron. F is the classic flanged version, while D is the foot-mounted version with a pump base for installation or mounting.
