Type SAP Single-stage Double-suction Horizontal Split Centrifugal Pump
General
Type SAP pump is single-stage double-suction centrifugal pump with horizontal split casing. It is widely used for water supply&drainage in fields of factories, cities, mines. Power stations and farmlands as well as water conservancy. It is provided for delivering clear water without solid particles or other liquid which is physically and chemically similar to clear water. The temperature of the liquid is 0℃~ 80℃. Permissible maximum inlet pressure is 0.6Mpa.
Performance range
Capacity Q: 72 ~ 20000m3/h
Head H: 6.8 ~ 186m
The description of pump type
For example 10SAP—6JA
10—The number obtained from the inlet diameter divided by 25 (inlet diameter is 250mm).
SAP—Single-stage double-suction centrifugal pump with horizontal split casing.
6—The number obtained from the pump specific speed divided by 10.
J—The rated speed is changed.
A—Outer diameter of impeller is changed.
Construction
Type SAP pump is horizontally installed, the casing and the cover of the pump are divided along the axis, the pump cover is above the shaft and the casing is under the shaft. The inlet and the outlet are on the casing under the shaft, the centreline of inlet and outlet is perpendicular to the axis. The rotor elements can be removed without disturbing inlet piping, outlet piping and motor, only dismantling the pump cover while maintenance. The other pumps adopt rolling bearings except type 48SAP—30 uses sliding bearings . The seal for bearing end cover is framework oil seal. The shaft seal uses packing one or mechanical one.
The direction of rotation
The rotation of the pump rotor is counter clockwise looking from the motor to the pump, i.e. the pump inlet is on the left and the outlet is on the right. The driver(motor) may be connected with the other end of the pump shaft according to customers' requirements too, meantime, the rotation, the direction of the inlet and the outlet are opposite to the above-mentioned .
The material of main parts of pump
The medium-contacting parts are made of cast iron. The material of the impeller may be cast steel or brass according to customer’s requirements.
Complete provision range
Pump, motor and coupling.
