USUN Model:US-MS-H-C Customized Closed cabinet Stainless steel frame Mini air driven liquid pump system with manual handle
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: M21-S liquid pump)
Air drive piston area ( 80mm Ø)
Hydraulic plunger area (16mm Ø)
Actual ratio = 25:1
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.
