examined after six months of operation or after 2,000 hours of operation. If the pump is used on fluids with solids, high temperatures or
other items that could cause accelerated wear, then this initial examination should be sooner.
After the initial examination of the internal components and wear items are measured, a specific maintenance schedule can be
determined. For best results, it is recommended that the pump be removed from service annually for examination.
MSDB Capabilities
Maximum Working Pressure:
Maximum Viscosity:
Maximum Temperature:
Maximum Noise Level:
Solids: Maximum particle size is 100 microns for slurries and 1/64" (.4 mm) for infrequent particles. Maximum hardness is 80 HS.
Maximum concentration is 10% by weight. If solids are being pumped, it is recommended that the pump have either ceramic or for best
results, silicon carbide components. Pumping solids may lead to increased wear.
Minimum Allowable Flow rate:
Do not allow the flow rate to drop below the minimum flow rate listed in the chart below:

Maximum Allowable Motor Power:
Do not exceed the maximum power rating for the pump coupling.
Standard coupling for the MSDB is 10-pole
6-pole coupling =
2 horsepower (1.5 kW)
8-pole coupling =
3 horsepower (2.2 kW)
10-pole coupling =
7.5 horsepower (5.5 kW)
135 psi (9.3 bar)
