Circulating Water Vacuum Pump

The series of recirculating water multi-purpose vacuum pumps use recirculating water as the working fluid to generate negative pressure through fluid jetting to create a vacuum.

It provides vacuum conditions for processes such as evaporation, distillation, crystallization, drying, sublimation, vacuum filtration, degassing, etc., and is especially suitable for laboratories and pilot-scale operations in industries such as universities, research institutes, chemical, pharmaceutical, biochemistry, food, pesticides, agricultural engineering, and bioengineering.

The working principle is the same as that of a benchtop pump.

Compared with benchtop pumps, it has a larger pumping capacity and is designed for applications requiring high vacuum extraction.

The pump has five independent suction heads that can be used separately or in parallel. When connected in parallel with a five-way manifold (optional), the combined pumping capacity is sufficient to meet the needs of large-scale rotary evaporators or reactors.

It features a dedicated motor with fluororubber seals, preventing corrosive gases from entering the motor.

The tank is made of polyvinyl chloride (PVC), and the outer shell is constructed from high-quality cold-rolled carbon steel plate with an electrostatic powder coating.

The jet nozzle is made of copper, while the three-way connectors and suction nozzles are made of polypropylene (PP), and the check valve core is made of polytetrafluoroethylene (PTFE).

The pump body and impeller are made of stainless steel plate (SUS standard).

It is equipped with casters for easy mobility and flexible placement in laboratories or workshops.

The water in the tank needs to be changed regularly to ensure water purity, maintain vacuum levels, and prevent scaling.

For applications involving corrosive gases, the water change cycle should be shortened.

SHZ-95B: The pump body and impeller are made of polypropylene (PP), with other features being the same as the SHB-B95.
