SIHImulti “MS” Series Flange Orientations


STANDARD CONFIGURATION• Suction sleeve bearing with external thrust bearing. • Direction of rotation – CCW ‐ HI

NON‐STANDARD CONFIGURATION• Two external bearing supports (on suction and

discharge side) – called “B” bearing design• Pump driven from suction side• Direction of rotation – CW ‐ HI• Price and lead time increase.

Best efficiency• low power consumption due to reduced re‐circulation in the balance line

Lowest wear rate

• because this system does not rely on tight, wear‐sensitive clearances to control the re‐circulation flow

SIHImulti MSL, MSM & MSC ‐ Patented balancing system advantages


Axial thrust is hydraulically balanced by mean of a combination of balance disc and balance drum

SIHImulti MSH – Thrust Balancing Design


Lift‐off Device creates a 1mm clearance between balancing drum and disc at low speeds preventing metallic contact. Recommended for VFD or service with frequent stops and starts

SIHImulti MSH – Lift-off Device

7000 series ball bearing

Spring‐loaded device


Integrated Temperature Compensation (ITC) allows for thermal expansion for high temperature applications. Allows for safe cold starts of the pumps.

Preventative Maintenance


Multi series pumps have their English version IOM’s

SIHImulti “MS” Series IOM Manuals


Follow installation and alignment procedures No piping loads on pump flanges Suction piping to pump must be in accordance with IOM recommendations Ensure proper rotation prior to initial start-up Operate pump on the pump performance curve. Avoid running at either end of the

pump curve for prolonged periods Operate pump within temperature and pressure limits of the pump Monitor pump operation. Investigate high temperatures or vibration problems. Liquids pumped should be clean without solids

SIHImulti “MS” Series Start-up


SIHImulti … Condition monitoring with SIHIdetect

Detect wear before damage occurs+ Cavitation and process turbulence+ Simple to connect+ LED display+ Available Ex+ All rotating machinery+ DCS integration and continual monitoring

Noise and Vibration analysis allows this compact deviceto diagnose the (often hidden) symptoms of longer termdamage even before vibration occurs.


Bearing Start‐up and Replacement – Grease Lubrication

• MSL, MSM, & MSC (Excludes 125 & 150)• The bearings will run hot for a day or so at

first start‐up or after re‐greasing• Normal operating temperature is

approximately 190º F• Roller bearings need to be re‐lubricated at

intervals specified in the IOM for each pump• The grease should be a lithium soap based

high temperature grease such a SKF LGHP2• “DO NOT MIX GREASES”

• Bearing should be heated prior to installation on shaft sleeve.

SIHImulti “MS” Series Maintenance


• MSH and MSL/M 125 & 150 only• New pumps are shipped from the factory without

oil in the bearing housing.

• Bearing housing must be filled with the appropriate type of oil, per the IOM, prior to starting

Bearing Start‐up and Replacement – Oil Lubrication
