High Volume Pumps & Boxes
Description
The HVLP pump delivers accurately measured quantities of lubricating oil to the divider block lubrication system for distribution to rod packing, compressor cylinders, power cylinders and various lubrication points on engines and compressors.
The pump is a plunger type with a 1” plunger stroke. The pump plunger is operated by an eccentric cam (single or double lobe) for the discharge stroke and by the plunger return spring for the suction stroke. The plunger is accurately fitted into the plunger cylinder for efficient operation at pressures up to 8,000 PSI.
Helical grooves milled in the plunger and radial bores in the cylinder regulate the quantity of oil delivered. The volume of oil delivered is varied by turning the plunger to different positions by means of the adjustment knob on the front of the pump.
Plunger and cylinder assemblies are closely fitted to ensure the pump will discharge oil at high pressures. As the plunger and cylinder wear, a small amount of leakage will occur past the plunger into the gear box. This is of no concern unless the leakage is sufficient to prevent the pump from producing the required pressures and oil volume.
The HVLP camshaft is supported by ball bearings and contains 2 single or double lobe cams which operate tappet assemblies to actuate the pump plungers.
Dual head HVLP Pumps deliver different quantities and types of oil from each pump head or the same oil from both pump heads.
HVLP Pumps must be supplied with oil under a slight head pressure (up to 50 PSI) to assure priming of the plunger cylinder during its suction stroke. This is accomplished by locating an oil storage tank above the pump, (gravity feed) or by supplying the pump with oil under pressure from the engine or separate oil system.
