Product Introduction

Main features

The main overflow parts of the heat preservation pump are provided with a hollow interlayer, and are provided with functions such as steam, heat / hot water, heat conduction oil, etc. to heat the conveying liquid and the pump, heat preservation and other functions. When the conveying viscosity is large, deceleration should be used Motors, speed-regulating motors or pulleys and other transmission methods to reduce the speed of the pump.

Heat preservation pump is designed for conveying the medium thickened, solidification or crystallization under normal temperature ans easy flow, such as asphalt, paraffin wax, rosin, heavy oil, resin and similar liquid, the temperature is not higher than 280℃.

Pump advantage

1.High precision ----- Under various temperature, viscosity and pressure conditions, it can ensure stable and repeatable flow rate, and the measurement accuracy is up to 0.3%.

2.Many seals to match application requirement, according to the different needs and the characteristics of the materials, packing seals and mechanical seals can be used, and according to the characteristics of the on-site materials, a sealed cooling jacket or thermal insulation jacket can be added

3.The coupling configuration is diversified. According to the site temperature and user requirements, elastic claw couplings, elastic pin couplings and diaphragm couplings (for high temperatures) are used.

4.Stable flow rate

5.No pulsation in output
