High Pressure Pumps Air driven high-pressure pumps
for up to 5,500 bar (79,750 psi)

MAXIMATOR high efficiency pumps are ideal for a broad variety of oil, water and chemical applications. MAXIMATOR pumps are air driven at a drive air pressure of 1 to 10 bar (14,5 to 145 psi). Basically the principle of operation is similar to a reciprocating amplifier where control of the piston at the end position is regulated by a pilot operated 4/2 way valve.

MAXIMATOR pumps feature a large air piston joint to a smaller diameter plunger. The pressure ratio is the difference of these two areas and is the method of determing maximum outlet pressure. Higher pressures are obtained by using higher pressure ratios. MAXIMATOR model numbers reflect the pumps’ nominal pressure ratios, while the technical data indicates exact ratios. The outlet pressure is easily to set through a simple air regulator. By multiplying the pressure ratio by the available shop air pressure, the nominal liquid pressure can be calculated.

MAXIMATOR pumps are self priming. In general it is not necessary to use an air line lubricator. The liquid to be pumped, flows into the suction chamber by the up-stroke of the drive piston. By this suction effect, the inlet check valve is opened and the outlet check valve is closed. The down-stroke generates the pressure at the liquid side. The inlet check valve is closed and the outlet check valve is opened by the generated pressure.

MAXIMATOR liquid pumps cycle automatically. When the pressure is built up the numbers of cycles slow down. The pump stops automatically when the output pressure forces are equal. The pump restarts with a slight drop in the outlet pressure or an increase in the air drive pressure. Pump performance can be effected by a number of conditions, such as freezing of muffler or pilot valves (which is caused by moisture in air lines), inadequate inlet air line sizes and dirty filters. Don’t reduce the indicated port sizes and consult
