Data Sheet Diaphragm Pump ZXM ZXRI 411.3

Diaphragm pumps Seybert & Rahier The new 4 series robust, durable, versatile, economic... sera - diaphragm pumps of series ZXM 411.3 and ZXRI 411.3 are oscillat-ing displacement pumps for delivery and dosing and feeding liquids in a variety of industries. Performance range between 2200 l/h and 3100 l/h, pressures up to max. 4 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 (ZXRI series) ???? low maintenance ???? low operating expenses ???? leakage-free ???? unlimitedly to run dry ???? easy to operate ???? designs according to ATEX ???? great suction heights * compared to common conventional diaphragms Diaphragm pumps Seybert & Rahier Design options The pump has two heads – technical data according to the performance schedule. The capacity of the ZXRI - type series can be set ma-nually at the integrated frequency converter. The ZXM-types run with constant stroke frequency. Therefore the capacity cannot be set. In ZXRF design they can be controlled via an external frequency converter so that their capacity can be adjusted to the process conditions again. Single diaphragm pump * The mechanically coupled working diaphragm acts directly upon the chemical. * Double diphragm design on request Single diaphragm pump Connection on suction side Connecting rod Dosing medium Working diaphragm Working diaphragm Dosing medium Connection on pressure side Diaphragm pumps Seybert & Rahier Technical Data Serie ZXM 411.3 Pump type Nominal capacity Max. counter-pressure Max. suc-tion height Inlet size Outlet size Nominal stroke frequency Driving power (motor) QN 50 Hz QN 60 Hz p2 max.

We have the optimum mate-rial* for each requirement. Pump body and valves: PVC, PP, PVDF, 1.4571 Valve balls: Glass, PTFE, 1.4401 Valve seals: EPDM, FPM, FEP-covered Working diaphragm: PTFE-faced * please ask us for any material required but not mentioned here Drive Each drive unit consists of a proven motor coupled to a stroke mechanism in a robust cast iron housing. sera – cast iron housings can cope with even extreme operating conditions due to the thickness of the mate-rial and the surface treatment. Control The capacities of the sera – diaphragm pumps are constant or infinitely variable. Manual capacity control via: ???? Adjustment of the stroke frequency Automatic capacity control, dependent on analogue or digital input signals via: ???? Three-phase motors with frequency converters Special designs ???? Diaphragm rupture monitoring device ???? Assembly of stroke frequency transmitter Accessories For the optimum installation of a dosing pump we can supply all the necessary accessories such as valves, pulsation dampers, injection fittings, dosing tanks, flow controllers, etc. against your order.
