Product Description Popular Usun Model :M130 Mini portable high pressure air hydraulic test pump for hose/tubes General Information for Air driven liquid pumps 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: M25 liquid pump) Air drive piston area ( 80mm ?) Hydraulic plunger area (16mm ?) 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. 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.Typical applications for air driven Liquid pumps Key featuresOne model available in 8 ratiosCompatibility with a variety of liquidsSafe pneumatic operationAluminum bodies and wetted materials of carbon steel or stainless steelRugged,compact,reliable and easy maintenance proven designHigh quality seals, long service life availableNo need for air line lubricationWide application with large range of pressure ratioMain technical data Typical technical data for air driven liquid pumps M serial Air liquid pump Technical data Base on air driven at 7 bar ,air consumption is 0.6-0.8 M3 per minBase on air driven at 7 BarModelPiston/Rod diameter ?(mm)Displacement per stroke (mL)Liquid INLiquid OUTMax outlet pressure Bar@ 8.3BarOutlet pressure(Bar) 1Bar=0.1Mpa=1.019Kg/cm20255075100150175200250300350400700Flow rate L/Min (L/min)M073021.21PT3/8"PT3/8"58.16.362.970.85 M102514.73PT3/8"PT3/8"834.423.831.620.59 M16209.42PT3/8"PT3/8"132.82.832.452.071.410.57 M25166.03PT3/8"PT3/8"207.51.811.571.330.90.720.60.420.12 M45123.39PT3/8"PT3/8"373.51.020.880.850.810.780.750.680.510.310.270.14 M64102.36PT3/8"NPT1/4"531.20.710.610.590.570.540.520.590.520.420.380.190.09 M10081.51NPT1/4"NPT1/4"8300.450.390.380.360.350.330.380.330.320.30.270.230M13071.15NPT1/4"NPT1/4"10790.350.30.290.280.260.250.290.250.240.230.210.170.12Remark 1) Maxium outlet pressure are at an air driven pressure of 8 bar or 116 PSI ,for long life usingof such pump ,we suggest that air driven pressure should be not more than 8 Bar Typical diagram of such air driven hydraulic pumps Product Applications Factory corners
