MSDTM Series

Theory and Operation

Technical Description

Multi-stage duplex (MSD) pumps are centrifugal

feed pumps designed for high pressure reverse

osmosis (RO) service. MSD pumps develop pressure by using a series of separate pump stages bolted together and mounted around a rotating

shaft. Each stage contains an impeller which

rotates uid with centrifugal force developing a

pressure higher than the initial input. Pressure

can be increased through the addition of stages or by increasing shaft rpm. An optional high pressure seal package is available for these

applications if pump inlet pressure exceeds

150 psi (10 bar).

Motors are selected according to equipment

operating requirements. A exible coupling allows the pump shaft to oat within the coupling

eliminating thrust against the motor. The inlet and discharge housings are designed to connect to grooved rigid piping with couplings. The

inlet housing itself can be attached to the pump in four di󰀨erent positions 90° apart. Precision

leveling feet support the pump stages along its length. All precision leveling feet are fully

adjustable to allow accurate motor and shaft

alignment.

Theory and Operation Continued

MSD Pump Internal Components

MSDTM Series

The internal components of an MSD pump can

vary depending on pump conguration and number of stages. Each stage uses a cen-

trifugal impeller with a spacer and wear ring to reduce internal leakage.

The WATER BEARING™ assembly is located at the discharge end of the pump. A balance disc rotates in the bearing carrier and serves as a thrust bearing for the pump. This unique design uses patented WATER BEARING™

technology which allows feed water to cool and

lubricate the balance disc.

WATER BEARING™

ASSEMBLY

As the motor rotates the pump, pressure di󰀨erences acting on the rotating impellers generate an axial thrust acting toward the motor. The

WATER BEARING™ employs the balance disc

to create a counter-pressure which exactly can-

cels the impeller thrust load. The bearing drain

line is used to produce the counter-pressure on

the balance disc. This thrust and counter-thrust allows the disc to “self-balance” based on oper-

ating conditions.
