Material of Construction
  • SS-316, SS-316 L, SS-304, SS-304L
  • Duplex stainless steel
  • Super duplex stainless steel
  • Hastalloy - B & C, alloy - 20 etc.....
  • Diaphragm - PTFE only
  • These are glandless and zero leakage pumps.
  • Flow rate is linear to stroke length variation.
  • Metering accuracy almost independent of back pressure.
  • Diaphragm is always balanced between the pressure exerted by the hydraulic oil & the liquid to be dosed, longer diaphragm life.
  • Automatic air bleeding from the hydraulic oil ensures better metering accuracy.
  • Arrangement of in-built pressure relief valve to protect the pump from pressure exceeding the rated pressure.
  • Rupture indication arrangement (ria) is an additional facility available with these pumps. these pumps with ria are provided with sandwich of two diaphragms. The rupture of any one of the diaphragms can be sensed by pressure sensing device.
  • In case of metering pumps to be used in hazardous areas the liquid head can be kept at a remote place from drive side. the head & drive are coupled by hydraulic oil in flexible tube.
Diaphragm Metering Pumps
  • Ronak Pumps offer a comprehensive range of hydraulically flexed diaphragm metering pumps for all gear size with capacity range of a few cc/hr to well over 7000 LPH with a maximum discharge pressure of 100 kg/cm2
  • These are hermetically sealed pumps as the plunger packing works in a safe and pure hydraulic fluid & rugged diaphragm (S) separate the hydraulic fluid from the metered fluid.
  • The double diaphragm and sandwiched diaphragm design-with diaphragm repture indicator prevents contamination metered fluid by the hydraulic fluid should one of the diaphragm ruptures.
The Advantages
  • Hermatically Sealed
  • Relif valve & Replenishing valve in hydraulic circuit
  • Relatively better to resistant to fouling
  • Long working life due to PTFE diaphragm & gentle flow against the diaphragm (S)
