General Description

Type SA,SAP pumps is single-stage double-suction centrifugal pumps with horizontal split casing. It's widely used in fields of factories, Cities, mines, power stations, farmlands and 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: 72~20000m3/h.

Head:  6.8 ~ 186m

Instruction of pump type
For example    10SA(SAP)-6JA

10-The number obtained from the inlet diameter divided by 25(inlet diameter is 250mm)
SA(SAP)-Single-station double-suction centifigual pump with horizontal split

S: 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.

The pumps is horizontally mounted, the pump casing and pump cover are divided along the axis. the upper is the cover, the lower is casing, the inlet and the outlet are on the pump casing under the axis, and their centerline is perpendicular to the axis, the rotor elements will be removed without disturbing the inlet piping, the outlet piping and the motors, only dismantling the pump cover while inspection.The shaft seal is either packing seal or mechanical seal(single end surface non-banlancing type).
The direction of rotation
The rotation of the pump rotor is counter clockwise looking from the motor to the pump, i.e. the inlet is on the left and the outlet is on the right. The driving end may be moved to another one according to customers'requirements, meantime, the rotation,the direction of the inlet and the outlet are opposite to the above -mentioned.

Material of main parts
The medium-contacting parts are made of cast iron.
The material of impeller: May be cast steel /brass /according to customer’s requirements.

Features of the SAP pump

1. The rotor elements are propped up with two bearing points, so it is stable and low noise in operation.

2.Double-suction impeller itself can balance thrust.

3.The shaft with changeable sleeve is protected from wearing and has a long life.

4.When you dismantle the cover and put it to a secure place, the rotor elements will be removed for inspection.

5. It's unnecessary to dismantle the inlet piping and outlet piping while maintenance.

6.Thre are packing seal and mechanical seal in seal ways, customer may choose it according to the requirements.

7.Remained water in the inside of the pump can be completely drained, so the pump is not damaged by frost in cold places.

8. The pump uses rolling dearings, it runs for a long life, it is easy for maintenance.

The material of main parts of pump

Pump, motor and coupling, common bedplate will be supplied when inlet diameter is less than 200mm.
