As sludge vacuum pump manufacturer in China, GN solids control produce 100% air operated vacuum pump with different treating capacity, including GNSP-10B, GNSP-20B, GNSP-40B.
How to operate the sludge vacuum pump with 40m3/h flow?

Firstly connect the air supply, normally air compressor which meets the pressure requirement, and manual mode or automatic mode can be selected as client’s requirement.
When automatic mode is selected, set the “automatic and manual switching valve” to the “zero position”, turn on the air supply, set the switching valve to the “manual state”, and set the “loading and unloading switching valve” to the “unloading state” to confirm the emptying of the material in the tank; Time 2 minutes;

Restore the “automatic and manual switching valve” to “zero position “, switch the “automatic and manual switching valve” to the “automatic state”, and the equipment can operate in automatic mode. The equipment will automatically suction and unloading according to the set loading and unloading time; (according to our experience, setting values for loading and unloading are 10s, which can be adjusted by users according to on-site conditions);
If manual mode is selected, set the “automatic and manual switching valve” to “manual state” and the “loading and unloading switching valve” to “unloading”;
Restore the “loading and unloading switching valve” to “zero position”; Place the suction port into the material to be sucked in
Turn the “Load and Unload Switching Valve” to “Load”, and the pump starts to suck materials when the tank is full; Turn the “Load and Unload Switching Valve” to “Unload”, and the pump starts to discharge slurry.
The automatic mode and manual mode can be only selected for GNSP-40B vacuum pump, the smaller size vacuum pump with only automatic mode. The vacuum pump can be used to transfer drilling waste from solids control equipments, drilling fluids, animal waste, sand, powder material, oil sludge, etc. material.
