We are offering hydro pneumatic press, hydro-pneumatic pumps(a low cost alternative to motorized and hand operated pumps) mercurys hydro-pneumatic pump range varies from pumping ratio of 1:3 and can go up to 1:260 i.e upto 1300kgf/cm2 pressure. the various models available are pneumatically operated single and double head pumps as well as electrically operated single and double head pumps. The mercury series of hydro-pneumatic pumps are ideal for applications such as : hydrostatic pressure testingcyclic pressure testingburst strength testingcentralized lubricationtransfer of coolants, electrolytes and other non-corrosive liquids operation of jacks, clamps and pressesportable systems for construction, mining and defense equipments. Some salient features of mercury hydro-pneumatic pumps are : 1. compact and light weight. Can be mounted in any orientation 2. low air consumption3. automatically compensates for leakages to maintain set pressure 4. can be used in explosive environments5. designed for use with water and other non-corrosive liquids6. in low pressure pumps, the discharge port can be rotated through 360 7. precise air pressure regulator to infinitely vary the output pressure8. automatic and adjustable lubrication through a unique mercury autolube unit
