Water Jet Suction Pump Valve

Water Jet Suction Pump Valve – Overview

The water jet suction pump valve can be used where the liquid is under pressure and is present as a propellant. It is used for transporting and mixing liquids. The water jet suction pump valve is self-priming and has no mechanically moving parts. The basic principle of the water jet suction pump is that the propellant liquid passes through a nozzle and draws in with it the liquid or gaseous medium from the suction line, increasing its velocity. The result is that the propellant and the medium are sucked in and mixed together. Suitable for use in aquariums, the chemical process industry, industrial water treatment, and swimming pools.

Valve handling Installation notes:

• We recommend installing the water jet pump between two detachable pipe sections.

• With a view to subsequent dismantling, it is useful to provide shut-off devices.

• Relaxation zones of at least 5 x DN are to be provided upstream and downstream of the pump.

• It is recommended to install a flow meter in the suction pipe to provide information on the suction power of the pump.

• It is useful to install manometers upstream and downstream of the jet pump for reading the inlet pressure and the back pressure.

• The suction time can be significantly reduced by installing a check valve in the suction pipe.

• Inlet and outlet pipes must have at least the nominal diameter of the pump.

• An exact dosing of the propellant and suction flow is guaranteed through the installation of throttle valves.
