Product introduction
CM,SHM,SEM series non self-p riming horizontal multistage centrifugal pump drives the fluid to rotate to complete the liquid transportation with the centrifugal force produced by the impeller of the rotary pump. The
series is equipped with non-standard customized motor, which mounted on the same motor shaft to connect the impeller, diffuser and mechanical seal tightly, and is installed on the bottom plate for connection.
CM,SHM,SEM series horizontal multi-stage centrifugal pump with back pullout construction adopts the structure design of axial thread inlet and radial thread
outlet. Its balanced impeller reduces the axial thrust of motor bearing and prolongs the service life of motor bearing . According to the special application and installation mode of household, industrial and construction service market, three design schemes of SHM, SEM, CM series provide a variety of solutions to
meet different usage habits.
The CM series is compact in design: it is directly connected to the motor flange through a separate stainless steel inlet body, and the 0-ring is used as the
sealing casing pipe to reduce the possibility of leakage . The segmental design of SHM, SEM series: the 0-ring externally mounted diffuser is tightly closed by the pull rod and screwed to the motor flange.

Pump operating conditions
• Pumping liquids which are thin, c lean, non-flammable,
non-combustible or non-explosive liquids, not containing
solid particles or fibers. l’lll
• Maximum ambient temperature: +40 °C
• Maximum altitude above sea level: 1000 m
•Totally enclosed, fan-cooled, 2-pole standard motors
• Enclosure class: I P55
• Insulation class: F
• Voltage: 3×220-240/380-415V
1×220-240V
•Available with single-phase motors(0.37kW-2.2kW)
• Normal temperature pump: -15°C to+ 70°C
• Hot temperature pump: -15°C to+ 105°C
• The motors used for the measurements are based on
2900rpm or 2950 rpm
• Tolerances to ISO 9906
• Measurements have been made with airless water at a
temperature of 20 °C l’lll
•The curves apply to the following kinematic viscosity:
=1 mm2/s
• Select a best efficiency of the pump which is operating
within the bold curve of the pump performance.
If the ambient temperature exceeds the 40 °C or the pump is installed at an altitude exceeding 1000 m, the motor output power P2 will decrease. In such cases, it necessary to use a motor with a higher rated output.
