Product Introduction

304 Stainless Steel Body, Safe and Reliable
1. The core components such as the pump body, gears, and pump shaft are forged from food-grade/industrial-grade 304 stainless steel, which is resistant to weak acid and alkali corrosion and is not prone to rust. The surface is polished, meeting the clean conveying standards of the food and pharmaceutical industries, and also possesses good mechanical strength, capable of withstanding certain impacts and high pressure.
2. Helical Gear Meshing Design, Low Noise and High Efficiency
Compared with spur gears, helical gears adopt a spiral tooth design, resulting in smooth and continuous meshing. The larger contact area leads to more even wear, extending the gear's service life and reducing fluid pulsation, ensuring stable and shock-free conveying.
3. Precise Clearance Control, Accurate Metering
The clearance between the gears and the pump chamber is controlled at the micron level. Combined with the volumetric metering principle, it can achieve high-precision metering of ±0.5%, meeting the process requirements of proportioning and quantitative feeding. The flow rate range covers 0.01~5 m³/h, supporting flow rate adjustment for different working conditions.

helical metering pump -1

The helical gear metering pump is precisely designed and manufactured through strict processes to ensure stable flow and no pulsation.

It is suitable for some industries with high precision requirements and high flow stability requirements.

helical gear metering pump -2

The helical gear metering pump also has good corrosion resistance and can adapt to a variety of different liquids.

helical gear metering pump -3

Typical Application:
1. Food and beverage industry: Quantitative filling and conveying of fruit juices, syrups, edible oils, and sauces.
2. Fine chemical industry: Proportioning and dispensing of additives, auxiliaries, and low-corrosive solvents.
3. Water treatment industry: Metering and dosing of flocculants and pH adjusters.
4. Mechanical manufacturing industry: Circulating conveyance and quantitative supply of lubricating oil and cutting fluid.
