High Pressure Pumps
Maximator high efficiency pumps are ideal for a broad variety of oil, water and chemical applications. They feature a large air piston joined to a smaller diameter plunger. The pressure ratio is the difference of these two areas and is the method of determining maximum output pressure. Higher pressures are obtained by using higher pressure ratios. Maximator model numbers reflect the pump’s nominal pressure ratios, while the technical data indicates exact ratios.  

Maximator hydraulic pumps cycle automatically. The pump stops automatically when the output pressure forces and the air drive 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 affected by a number of conditions, such as freezing of mufflers or pilot valves (which is caused by moisture in air lines), inadequate inlet air line sizes and dirty filters.

Please consult High Pressure Technologies for exact flow conditions not shown in charts. High Pressure Technologies offers complete technical and service support for all Maximator pumps.

CAUTION: While testing has shown O-rings to provide satisfactory service life, both cyclic and shelf life may vary widely with differing service conditions, properties of reactants, pressure and temperature, and age of O-ring.

Frequent Inspection Should Be Made to detect any deterioration, and O-rings replaced as required.

How To Select a Maximator Pump

  1. Decide on the type of fluid to be pumped.
  2. Determine the available minimum plant air pressure.
  3. Finalize the required outlet pressure.
  4. Determine the required flow rate. This can be done in a number of ways:

-Is the item to be pressurized pre-filled?

-What is flow rate required at no load for filling?

-What is flow rate required at pressure?

-What is volume of item to be pressurized?

-What is the time available to fill?

-What is the time to pressurize?

Flow rates for each pump, at various air drive pressures and outlet pressures, are provided on each pump page. These pumps run very rapidly at no load and slow down as pressure increases. The pump will eventually come to a stop at the “stall” pressure, which is the air drive pressure times the pressure ratio of the pump. At this “stall” point there is no flow and no air consumption. The pump will hold the outlet pressure indefinitely and will only stroke if the outlet pressure drops or the air drive pressure is increased.
