Self-priming Inline Vertical Centrifugal Ballast Water Pump
Maine Features
The EMC-type is solid casing type and is fitted to motor shaft rigidly. This series can be used for Line pump because the center of gravity and height is low and suction inlet and discharge out let of the both sides are in a straight line. The pump can be used as an automatic self-priming pump by fitting an air ejector.
Performance
* Handling fresh water or sea water.
* maximum capacity: 400 m3/h
* maximum head: 100 m
* Temperature range -15 -40oC
Application
Designed specifically for the needs of the marine pump markets, hydraulic performance extends to 450 m3/h of capacity and 130 m of head.
Line design for full 50/60Hz performance, speed up to 3550 rpm
On-piece solid casing and compact design give low weights of parts to be handled and for ease of installation, retrofit and optimal engine room layout. As a non-bearing design, it is an effective alternative to pumps with bearing problems.
The EMC design is optimized for low NPSH and good cavitation resistance. From the large size suction inlet flange, through the flow passage on the impeller inlet, the utmost care is taken to ensure low loss flow conditions.
Enclosed type with balance holes and replaceable casing wear rings reduce axial thrust loads and provide longer component life.
Common options included mechanical seal and soft packing.
Thanks to rigid coupled design, no pump/motor alignment required.
The motor frame is designed to assure that natural frequencies are well away from operating speeds. With large opening in the front of the motor frame, it is easy to dismantling the rotor unit.
Pump is able to self-priming by attaching a self-priming device on frame.
No heavy foundation required, minimum floor space ideal for retrofitting and debottlenecking. In-line suction and discharge simplifies piping design and construction.
Minimum number of parts to facilitate ease of assembly and disassembly. For added simplicity, the EMC series shares many of the same parts with ESC series.
