The rotary vane pumps, manufactured by Fluid-o-Tech® and
sold worldwide under the trademark Rotoflow®, are volumetric
pumps designed for pumping water and aggressive liquids with
low flow at high pressure.
Technical features and manufacturing characteristics
The housing and the rotor are in stainless steel AISI 303, while
the pumping chamber and the vanes are in carbon graphite.
Inlet and outlet ports are 3/8” GAS or NPT threaded.
A built-in adjustable relief valve to protect the pump and the
system from unexpected pressure spikes is also available upon
request.
The pump can be connected to direct coupling motors with a
stainless steel clamp or to M71 and M80 UNELMEC or NEMA
56C frame motors with the Fluid-o-Tech® coupling and adapter
set. Maximum operative temperature: 70 °C (158 F).
