Reverse Circulation Type Shielded Pump

Suitable for transporting liquefied gas, low boiling point and other easily vaporized liquids. Its feature is that the lubrication and cooling path is opposite to the basic type. This pump itself does not require an exhaust valve. The circulating liquid, after lubricating the bearings and cooling the motor, returns to the vapor phase area of the inlet tank through the reverse circulation pipeline at the rear of the motor, thus effectively avoiding cavitation, vapor lock and other phenomena, ensuring safe and reliable operation. It can be made into horizontal or vertical types according to the actual characteristics of the liquid to meet the needs of different customers.
