Flowserves MSP design bringsa new level of sophistication tolow flow, high head pump tech-

nology. Featuring a mediumspeed induction motor with arange from 2000 rpm to 8000rpm, the MSP delivers peakefficiency, excellent economy,simplified installation andreduced maintenance.

Design Features Advanced low flow,

high head performance Variable speed

motor-pump control Soft-starting of electric motor Elimination of step-up

gearbox and lubrication Elimination of throttling,

bypass or control valves Easy integration into main

process control circuit Complete electronic-electrical

packages for quick connection

to power supply Customized control solutions

including programmable

minimum flow protection

Typical ApplicationsLow flow, high headrequirements in:

Power Generation Boiler feedwater Condensate

Oil & gas production andhydrocarbon processing Feed Recycle Charging Transfer

Chemical processing andgeneral industry Transfer

Wash down andcleaning services

Options Inducer for lower NPSHR Horizontal configuration Two stage opposed impeller

configuration Materials

CA6NM Carbon steel 316 stainless steel Duplex stainless steel

Variable Frequency DriveReduced energy cost is achievedas no energy is wasted for throt-tling and the pump is running ator close to BEP. Other benefitsinclude: Elimination of gearbox

Optimal pump performanceover a wide range of serviceconditions

Manual control by selectingdesired speed

Optional, integrated PI controllerto adjust pump performance inresponse to physical parameterslike pressure or flow rate(Example: speed regulationbased upon a pressure setpoint can easily be established,

thus eliminating the need for athrottling control valve.)

Operating Parameters Temperatures from

-40C (-40F) to

200C (392F) Pressures to

100 bar (1450 psi) Maximum suction

pressure to 40 bar(580 psi)

Operating speeds from2000 rpm to 8000 rpm

Maximum flow at8000 rpm 25 m3/h (110 gpm)
