D- & F-Models Sliding Vane Pump

D- & F-Model Sliding Vane Pump Overview 
The D- and F-model sliding vane pumps have a working pressure of 350 psi (25.2 bar) are ideal for low flow applications involving light liquids. Unlike the CP-, CD- and Z-models, they do not have a replaceable cam but you can replace the sideplates. The internal relief valve is adjustable and there are a wide variety of mechanical sealing options. Available in a 1” inlet and a .75” outlet only.

The D-model sliding vane is a bare pump that can be close-coupled to any NEMA 56 or 66 C-face motor. With a close-coupled design, there are no special alignment requirements so installation is quick and easy. An F-model sliding vane pump is a frame mount design that is mounted to a baseplate and requires a coupling and coupling guard.
The D- and F-model pumps are suitable for LPG (propane & butane), agricultural ammonia, and many more liquefied gases as well as light liquids.
