Therefore, it is strictly forbidden to use the submersible electric sludge pump in reverse. So how to judge whether the submersible electric sludge pump is reversed? The way to judge the inversion is:
- Install a gate valve and a pressure gauge on the outlet pipe of the submersibleelectric sludge pump. When the submersibleelectric sludge pump is tested, the gate valve is closed, and forward start and reverse start respectively. The larger value of the pressure gauge is the forward rotation start. and record the pressure value for later judgment of reversal.
- If it is not convenient to install the pressure gauge on site, judge whether it is reversed by observing the outlet flow rate and testing the outlet pressure by hand.
Slurry pump is designed and engineered for complex heavy-duty pumping applications to handle high mixture densities such as sand, slurry, sludge, wastewater and gravels, etc. Submersible slurry pump is the kind of widely used slurry pumping equipment that is submerged into the fluid for slurry pumping applications, the submersible slurry pump can be directly powered by either a hydraulic or an electric motor assembled within a protective case which features combat structure, high efficient and flexible operation, etc. TAIAN OCEAN Pump Co., Ltd (OCEAN Pump) is the professional submersible pump manufacturer and supplier who has been dedicated to designing and manufacturing a complete range of heavy duty submersible pumps for over 20 years. Our main submersible pump products include submersible slurry pump, submersible sand pump, submersible dewatering pump and submersible dredge pump which can handle concentration of solids up to 60 percent. Product innovation, quality assurance and customer satisfaction are our long term commitment to our worldwide customers. Looking for worldwide dealers.
