Gear Drive Reciprocating Pump

Why Choose a Three-Column Configuration?

Unlike standard small-capacity pumps, this unit utilizes three phased piston banks driven by a common crankshaft.

Triple the Throughput: Delivers up to three times the flow rate of a standard single-column unit, significantly reducing your footprint and piping complexity.

Ultra-Low Pulsation: By staggering the suction and discharge cycles of the three columns, the pump virtually eliminates the flow pulsation typical of reciprocating pumps. This provides a remarkably smooth, continuous feed to your downstream vaporizers or filling systems.

Balanced Mechanical Load: The symmetrical three-column layout distributes the alternating mechanical loads evenly across the crankshaft and main bearings, dramatically reducing fatigue and extending the overhaul intervals.

Core Engineering & Structural Design

Based on a foundation of heavy-duty mechanical reliability, every component is built to withstand continuous 24/7 industrial operation.

Heavy-Duty Gear Reduction Drive: At the heart of the transmission is a rugged, high-torque gear reducer (FX series). Running at low speeds but generating immense torque, it dampens vibration and protects the motor. The belt-driven connection from the motor provides an additional layer of shock absorption, ensuring smooth power delivery to the crankshaft.

Rigid Structural Base: The entire assembly-motor, gearbox, and pump heads-is pre-mounted on a reinforced structural steel base featuring integrated lifting lugs. This anti-torsion design withstands the rigors of heavy road transportation and allows for rapid, precision leveling on site.

Precision-Machined Liquid Ends: Each of the three pumping chambers features independent, high-strength stainless steel liquid ends. The modular design allows for individual maintenance or replacement of a single column without dismantling the entire pump.

Built for Extreme Low Temperatures

Handling cryogenic liquids like Liquid Oxygen (LOX), Liquid Nitrogen (LIN), Liquid Argon (LAr), Liquid Carbon Dioxide (LCO₂), and LNG requires strict adherence to material science and safety.

Optimized Cold Ends: Designed specifically to handle extreme thermal contraction, the cold ends maintain a tight seal at temperatures dropping to -196°C, minimizing cold loss and preventing dry ice formation.

Advanced Safety Interlocks: The pump is engineered to integrate seamlessly with your control system. It supports comprehensive safety logic, including low suction pressure protection, loss of prime detection, motor/bearing temperature monitoring, and high discharge pressure shutdown (PHH).

Optional Explosion-Proof Integration: For hazardous environments, the unit can be equipped with certified explosion-proof motors, variable frequency drives (VFDs), and intrinsically safe instrumentation.
