General Information for Air driven liquid pumps

Hot Sale Usun Model: Us-Ah/2 Similar Haskel Pneumatic Liquid Pump Station for Burst Testing



 

USUN air driven liquid  pumps are ratio devices that utilize low pressure compressed

 

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

 

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

 

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

 

indicates exact ratios.  The outlet stall pressure is easy to set by adjusting the air drive pressure

 

through a simple air pressure regulator. 

 

By multiplying the pressure ratio by the available shop

 

air pressure, the nominal liquid pressure can be calculated.

 

Exmple ( Pump Model: AH40 liquid pump)

 

Air drive piston area ( 160mm Ø)

 

Hydraulic plunger area ( 25 mm Ø)

 

Actual ratio = 40:1


 

1.  AIR DRIVE SECTION

 

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

 

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

 

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

 

( forces fluid out of the liquid end).

 

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

 

2. HYDRAULIC SECTION (Wetted End)

 

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

 

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

 

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

 

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

 

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

 

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

 

inlet check valve closes and the discharge check 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

 

against this during operation. There are different materials and designs of high pressure seals

 

depending on the fluid being pumped and the maximum pressures of the pump, however the

 

standard seals are suitable for both water and hydraulic fluid use.

 

USUN air driven liquid pumps are self-priming, However, high ratio pumps are more difficult to

 

Prime and may require bleeding. In general, it is not recommended to use an air- line lubricator.

 

USUN  air driven liquid pumps cycle automatically  as the outlet pressure increases the

 

resistance  also increases and the cycle rate decreases until the pump stops automatically

 

when the output  pressure forces are equal. This is referred to as the stall condition.

 

The pump will restart with a slight drop in the outlet pressure or an increase in the air drive

 

pressure. Pump performance can be affected by a number of conditions, such as freezing of the

 

exhaust muffler or pilot valves (which is caused by moisture in air lines), inadequate inlet air-line

 

sizes and dirty filers. When operating the pumps on a continuous basis, we recommend you use

 

a maximum cycle rate of 50~60 cycles per minute.

 

This will both increase service intervals and assist in preventing ice forming

 

at the exhaust. An air supply dryer will also assist in reducing icing up.

 

To obtain best overall performance, it is recommended not to reduce the indicated port sizes

 

and consult We for flow conditions not shown in charts.
