Low Pressure Liquid Metering Pump Dosing Pumps are a highly efficient and safe high pressure pneumatic pumps, which apply to natural gas and compressed air as driven power in site. The injection pressure can reach 150Mpa (≈20,000psi) at maximum. Its chemical medium can be acid and alkaline when both the pump and pipeline are made of anti-corrosion stainless steel.
Our single and multi-pump packages are designed and fabricated in-house to maximize pump reliability and customer convenience. From a basic, tubular-frame, single-pump, single-point unit to complex, automated packages with multiple pumps, chemicals, injection points, and flow control criteria, we can design, build, and support it.
These chemical injection pumps are widely used in industries of petroleum, refinery, chemistry, power generation, pharmaceutical, sewage treatment, etc.
Characteristics
- Standstill of the pump when reaching the set final pressure
- Wide range of chemical additive media, such as anti-frozen agent, viscosity reducer, blocking remover, paraffin remover, etc.
- Good corrosion resistance when using special stainless steel, for example 316SS and 316L
- Substitute of leakage by automatic re-delivery through the pump
- Regulator to control inlet air supply
- High pressure bleed valve and high pressure outlet
- Simple air-driven pump, suitable to working condition of explosion proof request.
- Simple installation, reliable operation, easy to maintain
