Composite Material Gear Metering Pump For Various Hardening Agents

The composite material gear metering pump for various hardening agents is a device designed for conveying curing agents (such as epoxy resin, polyurethane, etc.) or composite materials.

It is suitable for chemical, pharmaceutical, food processing and other fields.

Its core function is to ensure the stable and efficient transmission of the medium during the curing process, while meeting special requirements such as corrosion resistance, high temperature resistance or high pressure resistance.

Typical application:

casting industry: 4-Toluene sulfonic acid

ammonium hydroxide: lipid and amine

organic chemical industry: acetic acid, oxalic acid

water treatment industry: PAC, PAM, hydrochloric acid, phosphoric acid, sodium hydrogen sulfife and hypochlorous acid

FAQ

1. Q: Why can this pump achieve precise metering?

A: This pump is a positive displacement pump. The volume between the teeth of a pair of meshing gears is fixed, and the delivery volume per revolution is constant. Metering accuracy is directly proportional to the gear speed. When paired with a drive device that allows for precise speed adjustment, such as a variable frequency motor or stepper motor, the delivery flow rate can be precisely controlled by adjusting the speed. Simultaneously, the insulation structure maintains a stable viscosity of the medium, reducing the impact of viscosity fluctuations on leakage, further ensuring metering accuracy.

2. Q: How to solve media leakage at the shaft end?

A: First, determine the seal type. If it is a packing seal, tighten the packing gland appropriately. If severely worn, replace the packing. If it is a mechanical seal, the sealing surface is most likely scratched or damaged by media impurities or aging, requiring replacement of the mechanical seal. If conveying high-temperature or corrosive media, replace with a double mechanical seal or install a sealing cooling/insulation jacket to improve seal reliability.
