[Three rain valve to recommend star products - mechanical seals] Description: submersible sewage pump with liquid level control means for automatic control. Types of liquid level control device other than the float level switch QY200-8-7.5 pumps, such as wastewater contained no or only small amounts of suspended impurities WQ100-25-11 pumps can also be used Submersible pressure sensors and supporting two second instrument. Liquid level control device installed in cesspool (sumps) should be as far away from the inner inlet. Single submersible sewage pump weighs more than 80kg cesspool indoor (sumps) manhole above the floor or beam should be embedded hook, lifting submersible sewage pump for use during installation and maintenance.

Calculate the water pump need to lift. Sometimes the customer to hit the ground transport distance also counted lift the pump, this is wrong, ground transport distance multiplied by the coefficient of friction after the order counted lift. 3, wear elbow pipe, pipe friction, etc. must be taken into account, the actual situation of these is different, is quite troublesome to calculate accurately, it is proposed to leave some space to ensure that the water pumps can play.
