WEBThe drive is directly connected to an integral pumping piston with inlet and outlet check valves. All three models use the area ratio of the large drive piston vs. the small pump piston to boost inlet pressure.

WEBThe following sections will give explanations and methods for trouble-shooting this series of pumps for the malfunctions noted. Each section will examine symptoms and indicate which things to check, so that disassembly and parts replacement are minimized.
WEBCheck for water and/or air in the air system. Clean and drain filter. If liquid in air exhaust is the fluid being pumped, first make sure the vent hole is not obstructed and then check the piston rod seals. If the seals are worn and need replacing, check the hydraulic fluid for abrasive contaminants.
WEBThe pump model number indicates the normal ratio between the area of the piston and either liquid plunger. See “Principle of Operation” in the LP-GL catalog.
WEBIt provides a means of boosting plant air to higher pressure and relatively low flow requirements. It is a bootstrap ratio pump that employs the energy of compressed air to raise the pressure of part of the air supply. The ratio …
WEB2.3 Liquid Pump Section(s) Refer to the detailed assembly drawing provided with each unit. Each pumping section consists of a plunger or piston assembly with high pressure dynamic seals, retainers and bearings, all enclosed by an end cap incorporating inlet and outlet check valve assemblies.
WEBOperation. The pump model number indicates the ratio between the area of the air piston and the liquid piston. See “Principle of Operation” in the MLP-46 catalog. The liquid outlet pressure can be controlled quite accurately by regulating the air drive pressure.

WEBTo install upper and lower sets of rod seals and bearings: Fit 568116-7 O-rings firmly around 26165-2 seals. Tilt seals into 16778 body as shown, so O-ring will face bearing. Squeeze 27908 bearing so that ends overlap. Insert into 16778 body and allow to expand into cavity. Insert piston rod through bearing section with rod insertion tool 56198.
