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.

  • Self priming
  • Dry proof
  • High suction capacity
  • No electric components
  • Discharge outlet with protection
  • Solid external sturcture
  • Vast compatibility of fluid media 
  • Reduced internanal volume minimize the waste and easily clean
  • Stainless steel bolt are corrosion resistant, and offer you reasonable positioing and conveniently reassemble
  • Unique designed three way control valve ensure no block operation, easily parts maintenance, no need lubrication for air pipeline
  • Worn resistance parts ensures precisely positioning of stem and fast replacement

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.
