Operating instructions for MAXIMATOR pumps

1.1 Technology
The MAXIMATOR Pump described below is a slide-valve piston that is driven by gaseous
media and has been especially conceived for offshore applications. It can be employed in
the pumpage and compression of water or oil. Its construction resembles a pneumatic
cylinder.
The pump coefficient denotes approximate ratio between drive pressure and working
pressure.
The connection for the drive medium (Marking P
L
) is located at the bottom cap of the
flanged-on servovalve casing to which also the silencers are fixed. The pressure nozzle
(Marking P) is located laterally at the HP location of the pump.
The pumps are designed in such a manner that medium is pumped in both travel
directions of the HP piston which provides them with a high pump capacity. The intake
(Marking S) is arranged in longitudinal direction. The bottom cap has a bore to discharge
any leakages of the drive or compression medium.
The pump runs automatically and is driven by a floating slide valve that reciprocally admits
pressure or vents the drive piston. The control system operates without any springs or
interlocking because pressure is admitted reciprocally the floating slide valve.
Major components of the hydraulic part are the pump head, piston rod with HP piston, HP
sealings with back-up rings and the non-return valve at the suction connection.
