Cenlub industries offers single-shot centralized lubrication system, model h-600-6 for machines/machine tools. This pump has its own reservoir; it is of piston type where the piston is actuated by a cam, integral with the handle of the pump. On operating the handle, the pump discharges oil. As soon as the pulling force on the handle is released, the piston returns back by spring force and the pressure in the lubrication line is reduced to 1 kg/sq.Cm. There is an in-built check valve and pressure reducing system incorporated in the pump. The pump is equipped with a relief valve, which safeguards it from overloading. It is fitted with an oil window to cross-check the level of oil in the pump and to refill the reservoir from the top opening, once the oil level is nearing the minimum. The pump is also equipped with a suction strainer at the inlet and a drain plug at the bottom of the reservoir. Suitable holes are provided for vertical mounting of the pump. The pump outlet is suitable for 6 mm dia tube. Specifications: pressure - 18 kg/cm2; discharge - 6 cc per stroke; reservoir capacity - 600 cc; material of reservoir - aluminium casting; suitable for oil with viscosity - 32 - 460 cst/40ºc; and best suited for medium size machines.
