Descriptions
A single piece polypropylene center section for increased
reliability and chemical compatibility, plus high-reliability
modular air valve. The overmolded frame for improved reliability
and will help to eliminate fluid leakage and new generation of
diaphragm design that increases flow with flow rates up to 265 gpm
(1004 lpm) - making it one of the most efficient pumps on the
market.

Comptetitve advantage
The air-driven double diaphragm transfer pumps. No electrical
components are required because the pumps are
air-driven. RD series pumps are run-dry safe and self-priming. The
pump capacity can be controlled by changing
the pressure in the air supply. The air control is designed for
oilfree operation. The RD series pumps are ideally
suited for the transport of liquid chemicals. It transports media
at up 6,700 l/h and up to a discharge lift of 70 m.
As the pump capacity is highly dependent on the back pressure, the
performance curve must always be observed.
At the sametime, the differential pressure between the hydraulic and
pneumatic sides should not exceed 2 bar.
Higher values reduce the service life of the pump. When selecting
pumps, check the material compatibility.
In addition, consider the density, viscosity and temperature of the
transported medium.
