This lpg multistage pump is a centrifugal flow-channel pump with horizontal design and 8 stages. It adopts mechanical seal without external cooling. Equipped with a pre-compression turbine at the suction end, this lpg multistage pump performs excellently under low NPSH conditions, offering high flow rate and high pressure.
The pump consists of four main components: support section, drive section, bearings, and sealing components. The support section is composed of the inlet support frame, outlet support frame, front guide vane sleeve assembly, guide vane baffle, guide vane sleeve assembly, outlet connector, cover, and bearing housing – the outlet connector uses tie bolts to clamp each section together to form the working chamber. The drive section consists of the drive shaft, front-stage impeller, copper impeller, and parallel key – the shaft drives the impeller through the key to generate centrifugal force. The bearings include front guide vane sleeve bearings, guide vane sleeve bearings, and rolling bearings. The sealing components are made up of O-rings and mechanical seals..

This lpg multistage pump features horizontal design with 8-stage impellers, delivering high head and large flow output. The mechanical seal requires no additional cooling system, simplifying installation and maintenance. The pre-compression turbine at the suction end effectively reduces NPSH requirements, ensuring stable operation even under poor suction conditions. With compact structure and smooth operation, this lpg multistage pump is suitable for continuous heavy-duty service.
This lpg multistage pump is suitable for cylinder filling, pumping LPG from above-ground storage tanks, and tanker truck loading and unloading. It handles a variety of media including LPG, kerosene, diesel, and other liquids.
Q1: Why does the lpg multistage pump not operate?
A1: Check the motor and inspect the pump body for jamming (foreign objects or unbalanced tie bolts).
Q2: Why does the lpg multistage pump vibrate heavily?
A2: Check alignment between motor and pump – verify mounting nuts and center height consistency.
Q3: How to fix leakage from the lpg multistage pump?
A3: Check the mechanical seal (damage or incorrect height – standard 2.5mm±0.5mm) and inspect O-rings for wear.
