China Air Liquid Pump Air Driven Liquid Pump Air Liquid Pressure Pump

Popular Usun Model :AT typehose or pipes or valve air driven liquid pressuretesting pump General Information for Air driven liquid pumps

USUNair driven liquidpumpsare ratio devices that utilize low pressure compressed

airdriving a larger diameter piston (area x pressure) which is linearly connected to a smaller

hydraulicpiston/plunger. Using this ratio principal, a higher hydraulic pressure can be generated.

UsunPump model numbers reflect the pumps nominal pressure ratio, while the technical data

indicates exact ratios. TheShaft outlet stall pressure is easy to set by adjustingCar Electronics the air drive pressure

through a simple air pressure regulator.

By multiplying the pressure ratio by the available shop

airpressure, the nominal liquid pressure can be calculated.

Exmple ( Pump Model:AT644liquid pump)

Air drive piston area (160mm Ø)

Hydraulic plunger area ( 20mm Ø)

Actual ratio = 64:1

1. AIR DRIVE SECTION

The air drive section consists of a light weight piston complete with seals running inside an

aluminumbarrel. The diameter of the air piston is 80mm. When compressed air is supplied to

the pump the airpushes the air piston down on a compression stroke

( forces fluid out of the liquid end).

Under thecontrol of pilot pins (poppet valve) triggered at each end of the stroke

2. HYDRAULIC SECTION (WettedEnd)

The hydraulic section of an air driven liquid pump consists of 4 main pieces, the hydraulic body,

thepiston/plunger, the check valves and the main high pressure seal. The hydraulic

piston/plunger isdirectly linked to the air piston and it is housed inside the hydraulic body and

its movement up anddown creates the liquid flow into and out of the pump through the check

valves. The check valves arespring loaded and on the suction stroke the inlet check valve

opens to the maximum allowing fluid intothe hydraulic body and on the compression stroke the

inlet check valve closes and the dischargecheck valve opens forcing the pumped fluid into the

process. The main high pressure seal is located within the hydraulic body and the piston/plunger seals

againstthis during operation.There are dGift Box & Bag ifferent materials and designs of high pressure seals

Remark 1) Maxium outlet pressure are at an air driven pressure of 8 bar or 116 PSI ,for long life using

of such pump ,we suggest that air driven pressure should be not more than 8 Bar
