L1S Series Single-Acting Air-Driven Liquid Booster Pump

CDI-L1S single-acting air-driven liquid booster adopts built-in single air-controlled unbalanced distribution valve for automatic reciprocating cycle. The air drive body is made of black oxidized aluminum alloy for anti-rust; wetted body can be carbon steel or stainless steel as per process fluid. All seals are imported premium parts. Drive piston diameter:100mm, max allowable drive air 10bar, recommended operating drive pressure ≤8bar for long service life. Driven by compressed air to generate high hydraulic pressure.

Core Advantage

  • Auto on-off cycling design; pump stops automatically at set pressure and restarts for pressure makeup once leakage occurs;
  • Black oxidized aluminum air housing with good corrosion resistance, customizable wetted material;
  • Imported sealing set ensures stable sealing performance and low failure rate;
  • Hydraulic output changes proportionally with inlet drive air pressure for easy regulation;
  • Spark-free full pneumatic construction, safe for explosive hazardous area; Min startup drive pressure:3bar, standard working range:3~8bar;
  • Compact lightweight design with unified G3/8 drive port for all models, easy installation & maintenance.

Application

  • Static & burst pressure testing for valves, pipe fittings and pressure vessels;
  • Hydraulic clamping power for valve test bench fixture;
  • Lubricant filling for mechanical equipment & refrigerant cylinder filling;
  • High-pressure liquid transfer in flammable & dangerous working environments.
