4" coupling 250 bar 6 bar 125 (l/min) J4" quick coupling %" quick coupling ||||||||||||||||||||||||||||||||||I1 Portable submersible pump type MSP-EH 16-200 The MarFlex submersible pump EH 16/200, (-Mono pump), is a hydraulic drive, eccentric helical pump, that uses the positive displacement principle, and is especially designed to cope with high viscous cargoes like: • molasses • lubricating oil additives • unheated fuel oil • clay slurries The pump can be used via a standard 12" tankcleaning hatch and can be driven by the ship's hydraulic system or a portable powerpack. The pump consists of a rotating element (worm or rotor) and a static element (stator). The rotor (chromium steel) is shaped as a worm and has a relatively coarse pitch. The stator (NBR rubber) has the same shape but with a pitch which is exactly half as coarse as the pitch of the rotor. This difference in pitch creates the so-called 'chambers' between the rotor and stator. As soon as the pump starts running these chambers will move from the suction side to the pressure side of the pump and accordingly the cargo will move in the same direction. The seal between the stator and the rotor always exists and is independent of their position with regard to each other. This means that at any position of the rotor the pressure side is always separated from the suction side. The maximum discharge head of the Mono pump depends on the deformation (due to the NBR material) of the stator.
