▪Hydraulic pump efficiency (%) with trimmed impeller: see data sheet
▪Pump performance curves, including efficiency characteristics: see documented
characteristic curve
▪The efficiency of a pump with a trimmed impeller is usually lower than that of a
pump with the full impeller diameter. Trimming of the impeller will adapt the
pump to a fixed duty point, leading to reduced energy consumption. The
minimum efficiency index (MEI) is based on the full impeller diameter.
▪The operation of this water pump with variable duty points may be more
efficient and economic when controlled, for example, by the use of a variable
speed drive that matches the pump duty to the system.

Fig. 2: Sectional drawing of example: UPA 100C
Pump and motor are connected by a sleeve coupling. The stage casings are supported
by a pump shroud, by straps or stud bolts. A suction strainer protects the pump from
coarse particles in the fluid. The pipe is connected via a non-return valve or
connecting branch, with either internal thread or flanged ends.
The fluid flows along the motor and enters the suction casing (2) through the suction
strainer (1). It is accelerated outward by the suction impeller (3). In the flow passage
of the stage casing (4) the kinetic energy of the fluid is converted into pressure
energy, and the fluid is routed to the next impeller (5). This process is repeated in all
stages until the fluid has passed the last impeller (5). It is then guided through the
integrated non-return valve to the connection branch (7), where it leaves the pump.
The integrated non-return valve prevents uncontrolled backflow of the fluid.
4.7 Scope of supply
