Series Introduction 1: Plunger Series

Hydraulic end performance of plunger metering pump
High controllable pressure, high metering accuracy, simple structure, convenient maintenance, wide application range, high practicality and economy. High temperature ceramic spraying plunger (Note: when the transmission medium exceeds 100 ℃, HZHD adopts stainless steel chrome plated plunger); With packing automatic reset system: when there is a gap between the packing and the plunger due to wear, the automatic reset device can immediately adjust to the original working state, so as to effectively avoid medium leakage.

When the conveyed medium needs to be insulated or cooled, the plunger pump head with insulation jacket can be used.

Heat preservation and cooling jacket plunger pump head

It is a specially designed plunger metering pump. The liquid cylinder body and the inlet and outlet are equipped with heat preservation and cooling sandwich shells, which can be used for special heat preservation or cooling of the transmission medium. At the same time, its sealing chamber is equipped with a heat preservation or cooling jacket, and the temperature of the sealing chamber is controlled by conveying heat preservation or cooling medium to the jacket. Steam insulation has the characteristics of stable heating and small temperature difference of transmission medium. It is mainly used to transport medium that needs heating or has large viscosity and viscosity decreases with temperature rise. Special thermal insulation design can also be carried out according to the needs of users. The specially designed shell jacket and sealing device are applicable to the transmission medium that is easy to crystallize and needs thermal insulation.
