Many customers are interested in the sludge and solids vacuum transfer pump that GN Solids Control manufactures. They can review the specification as provided on GN Solids Control website. And also, they can contact GN Solids Control sales managers to get information.

As it is high 100% air driven pump with big vacuum pressure, many customer may have some questions about the pipeline connections of the vacuum sludge transfer pump. They may wonder: What is the maximum pressure head (height) that GN made sludge and solids vacuum transfer pump can suck from? Clients may actually look for a vacuum pump that can lift sludge and slurry from at least 50m and discharge 1000m. They wonder if GN Solids Control has a model that meets this requirement? If yes, they could want to get more supporting technical specification.

As clients can see from the information showing on GN website and the sludge and solids vacuum transfer pump brochure. The big size sludge and solids vacuum transfer pump GNSP-40B can meet the requested applications. The maximum vacuum pressure is 85Kpa that means, the maximum suction depth is 8.5 meters for water.

And the head or lift of the pump for water is 80 meters. But if horizontally, the suction length is up to 50meters and the discharge distance is up 1000.
Please answer the questions as enclosed, we will understand if our pump suits you or not.

Take the model GNSP-40B sludge and solids vacuum transfer pump for sample, the vacuum pump connection information are as following:

1) Suction hose: 4”. With DN100 fast connector at both ends. Wear resistance material, can withstand negative pressure 85kpa

2) Dischare hose: 4”. With DN100 fast connector at both ends. Wear resistance material, ressure 1.0Mpa

3) Air hose: 2”. Pressure 1.0 Mpa

4) 90kw air compressor is recommended for GNSP-40B sludge and solids vacuum transfer pump. Enclosed is some specs for your information.
