Description: Hand operated piston pumps are suitable for manual centralised lubrication system of light duty automatic machines such as small power presses, packing machines, milling machines, single spindle automats, looms, surface grinders and pouch fillings machines. Normally these pumps are suitable for 2-40 lubricant points. These pumps are very simple in construction. The construction is spring return piston type with the piston operated by pulling a cam handle. The other salient features are strainer at the inlet port and a pressure reducing system that is very important for proper operation of metering cartridges. Clean oil is to be filled always to get better life and troublefree operation of these pumps and dry pumps are not recommended. Pumps are suitable for oil with viscosity range 40-1000cst.
