Data Sheet Diaphragm Pumps R4xx.2

Diaphragm pumps Seybert & Rahier The new 4 series robust, durable, versatile, economic... sera - diaphragm pumps of series 409.2 and 410.2 are oscillating dis-placement pumps for dosing and feeding liquids in a variety of industries. Performance range between 0,4 l/h and 1450 l/h, pressures up to max. 10 bar. Application Liquid chemicals with aggressive, odorous, abra-sive, radioactive, flammable, viscous or toxic properties. ...futher features of performance ? high dosing accuracy ? long service life of diaphragms* ? high-quality materials ? linear control characteristic ? low maintenance ? low operating expenses ? leakage-free ? unlimitedly to run dry ? easy to operate ? designs according to ATEX ? low weight * compared to common conventional diaphragms Diaphragm pumps Seybert & Rahier Design options The single pump has one head – technical data ac-cording to the performance schedule. Multi headed or combination pumps with a single drive are reasonably priced – combination pumps with each pump head sized individually according to the requirements in respect of material, size and con-trol. Single diaphragm pump The mechanically coupled working diaphragm acts directly upon the chemical. Double diaphragm pump In order to protect the working diaphragm from chemical attack and for additional safety an interme-diate diaphragm is fitted. The action of the working diaphragm is transferred hydromechanically (via a buffer fluid) to the intermediate diaphragm. This construction principle is well-known today – but originally a sera - patent Single diaphragm pump Double diaphragm pump Working diaphragm PressurevalveIntermediatediaphragm Connecting rod Dosing medium SuctionvalveBuffer fluid Diaphragm pumps Seybert & Rahier Technical Data Serie 409.2 Pump type Nominal capacity max. counter-pressure max. suction height Inlet-/Outlet-size Driving power (motor) Nominal stroke frequency QN 50 Hz QN 60 Hz p2 max.
