* The maximum flow rate is a value determined by means of a test bench and measured with water at a liquid temperature of approx. 20 °C . The measurement is taken at the pressure joint of the pump, without hose, nozzle or flow meter. The achievable flow rate in use is lower and depends on the individual application, the liquid properties and the configuration of the pump. The max. delivery head also depends on the pump design, motor and fluid. The viscosity values are determined with oil.
** Test assembly: Medium water / diesel, flow in preferred direction, settling section 0.2 m upstream and downstream of flow meter

Hose connection
for plant feeders and large-scale industry
Description:
The hose connection connects the delivery hoses to the pressure/suction nozzles of the double diaphragm pumps or the dispensing nozzle. When using a double diaphragm pump, either a suitable reducing nipple or a threaded bottle must be used in addition to the hose connection.
Special connections are available on request

Pulsation damper PD I D
for plant feeders and large-scale industry
Description:
The pulsation dampers are containers filled with a gas cushion. A diaphragm separates the gas cushion from the system fluid. Pulsation dampers store and discharge part of the stroke volume in the stroke rhythm of the double diaphragm pump, whereby the gas cushion is compressed or decompressed accordingly. This makes the pulsating flow rate of the pump almost uniform.
Adjustable air control
Materials: PP / PVDF / stainless steel
Features & advantages
Connection type on the medium side: 2" IG
Connection type on air side: 1/4" AG
Max. operating pressure 10 bar
ensure almost uniform volume flow, which increases the accuracy of flow meters
Compensation of pressure surges (water hammer) protects installed fittings
Prevents pipe vibrations that cause material fatigue and pipe breakages
