According to the temperature, pressure, presence or absence of particles and the viscosity of the liquid to be transported, the shielding pump can be divided into ordinary type (basic type), reverse circulation type (reverse circulation type), high temperature type, high melting point type, Pump type, pneumatic diaphragm pump type, electric diaphragm pump type, self-priming type, mud separation type, and various types of shielded pump designed for ships, nuclear power plants and absorption refrigeration equipment.

Punch grab Rob here! ①ordinary type (basic type) Mainly used for conveying vapor pressure is not high, the temperature is not high, non-particle media. In general, the transmission medium temperature does not exceed l50 ℃, the basic type of single-stage impeller can reach 220m. ② reverse circulation type (reverse circulation type) This type of shield pump uses a high pressure within the impeller with the internal circulation structure, suitable for the transport of easily vaporized liquid, sometimes also called easy vaporization type, as shown in Figure 2-16 .
