The compact, low-cost MAXIMATOR High-pressure Pumps are driven by air or noble gas pressures between 1 bar and 10 bar. There are numerous potential applications for MAXIMATOR Pumps in machine engineering, oil and gas industries, chemical and pharmaceutical industries, defence, mining and the construction industry as well as in aviation and aeronautics.
MAXIMATOR provides competent consultancy, engineering design and supply of complete systems to optimally and economically solve your testing tasks and offers you extensive Services.
MAXIMATOR Pumps are available in 5 sizes: M, S, G, GX, DPD. The sizes vary according to their suitability for different pumping media, wide ranging flow rates and their maximum allowable operating pressures. MAXIMATOR provides the best-suited fluid pump for each application.
MAXIMATOR pumps can, in principle, be installed in any position, but a maximum service life of the seals is achieved in a vertical one.
Port sizes Important!
Please observe that only screws and tubing are fitted that are suitable for the pressure range of the pump. To ensure an optimum operation (pressure and flow) of the pumps, the port sizes of the pumps shall not be reduced.
The air drive connection is located at the spool valve housing. A second air drive connection as unregulated pilot port on S…D and G(SF) series that has to be connected too, not only provides better pressure control but is also the ideal place to install control instrumentation because of its small size. In any event a compressed air filter and water separator has to be fitted to the pump. Filters with water separator, pressure regulator, control pressure gauge and shut-off valve are optionally available under ”Air control unit C….“, depending on the pump line.
No air lubricator is required since the pump received Barium grease treatment. Has a lubricator been used once, it is strongly recommended to continue. If there is only very dry air available, an air lubricator is needed.
are in general between –20°C to +80°C (standard). The pumps with –VE seal version can be operated up to max. +60°C, at short term up to +80° would be acceptable. For outdoor service at temperatures of 0°C and below, special versions are available on request.
Proper operation and efficiency of the pumps is mainly depending on the quality of the used hydaulic liquid. We recommend hydraulic oils with a viscosity between 46 – 68 cst, i. e. Manufacturer Hydraulic oil to DIN 51524 T2; DIN 51519; ISO VG 46

| ESSO | NUTO H 46 |
| SHELL | TELLUS Oil 46 |

The drive air should have a quality class of 3 to 4 (solids/water/oil) according to the recommendation no. 611/1984 by PNEUROP (European Committee of Manufacturers of boosters, vacuum pumps and air driven tools).
Please note that by using humid air of high humidity in continuous operation the problem of icing could occur. We suggest to install a water seperator and a dryer in the drive air line. If the drive air is too dry and has got a dew point lower than – 40°C, we suggest to use an oiler. By observing this drive air quality, an optimum life time of the seals and packings will be achieved.
MAXIMATOR pumps are suitable for liquid applications. To select and order a hydraulic pump that is suitable the best for your applications, the following parameters have to be observed:
1. Liquid to be handled
The type of liquid is essential to select a MAXIMATOR pump hence the wetted material of construction and compound of the seals are determined by the specific fluid. MAXIMATOR pumps are available for several services. The two most important we are offering standard pumps are for oil or water use, see also ordering codes.
2. Available Air Drive pressure
MAXIMATOR pumps are designed for an air drive pressure of pL = 1 to 10 bar (14,5 to 145 psi) maximum.
3. Required hydraulic outlet pressure and flow capacity
The outlet pressures given in the technical pump tables are based upon a maximum air drive pressure of pL = 10 bar. The real oulet pressure in your specific case is determined by air drive pressure multiplied by pressure ratio, pL * i. The indicated flow capacities Qmax is the maximum value which can be reached at an outlet pressure of 0 bar and an air drive of pL = 6 bar. The real flow capacities at a specified outlet pressure are listed in the flow charts, page 20 to 23.
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
