Lubomatic hand pumps manufactured and offered by skey products, are available in a wide range for oil lubrication. These pumps are operated by hand levers. The piston moves up and forces oil out through the delivery pipe. The return of the piston is by spring. During this stroke the oil is sucked inside the cylinder and is then forced out, when the handle is operated. There should be delay before one operates the second stroke. The oil must be clean. A sight glass is provided on the front side. If the oil level goes down below the center in the sight glass, the oil should be filled. The hand pumps are offered in two models, viz, lhp-500-6 and lhp-1500-10. Model lhp-500-6 has aluminium or acrylic reservoir of 0.5 l capacity, with discharge at 6 cc/stroke. The outlet pipe connection is suitable acrylic reservoir of 1.5 l capacity with discharge of 10 cc/stroke. Outlet pipe connection is suitable for 6 od piping.
