Liquid jet pumps are jet pumps operating on the ejector principle which suck a liquid by means of a motive liquid jet, mix the motive and suction flows and convey the mixed flow.
Advantages

- ide range of materials such as steal, stainless steal, cast iron, bronze, Teflon and graphite
- Low cost
- May be installed in any position
- Self-priming
- Simple and reliable
Applications
- Acidifying/causticizing oils
- Conveyance and mixing of fluids and suspensions in the chemical and pharmaceutical industry
- Conveyance of dirt water, sewage, slurry or sludge in water, sewage, building and other industry
- Conveying and mixing acids or lyes in water and effluent treatment plants
- Draining of cellar rooms
- Introducing antiknock agents and colouring additives to gasoline
- Proportioning chemical solutions and diluting acids and alkali to a definite end concentration
- Pumping out of foundation pits
Materials
- Cast iron
- Cast stainless steel
- Other materials on request
- Steel or stainless steel
- Temperature change resistant porcelain
Installation Requirements
- The connection pipes have to be of at least the same size as the connections of the water jet pump
- The pumps have to operate against pressure. Therefore, it is recommended to install a non return and a throttle-valve after the water jet pump.
- The cleaning of the water jet pump is done by closing the throttle-valve after the pump. The driving water flows through the suction pipe and removes impurities.
- A bend in the discharge pipe can prevent backflow
- In case of conveying slurry and sludge It is recommended to provide rinsing water because the suction medium has to be flowable.
- The slurry suction pipe should be installed straight between jet pump and vessel. In case of a blocked suction pipe it is easy to clean after removing the cleaning cap.
