The instruction of main parts

A) PUMP CASE: foot support structure and spiral volute chamber, with volute chamber, foot, influent flange and discharge flange cast into an integrity. The flanges may be drilled accordance with international stand ISO 2084 DN16 or as requirement.

B) IMPELLER: Closed impeller designed in the excellent hydraulic model to guarantee pump performance and efficiency. The dynamic balance test shall be conducted.

C) SUSPENSION FORK: the suspension fork is installed with bearing inside. There are totally 6 bearing specifications for the whole series. The bearings shall be lubricated by lubricating oil (for some specifications) or grease.

Construction (pump structure & material)

Operation 

1. ELECTRIC MOTOR DRIVE

Install a starter with overload protection to prevent the motor being damaged by overload.

The overloads should be set so that they trip if the current exceeds the normal current of the

motor (see motor nameplate) by 10%.

2. BEFORE STARTING

The pump is ready for starting when:

a) Pump base-plate is grouted and bolted to the foundation.

b) Pump and driver are correctly aligned.

c) Bearing lubrication is provided.

d) Stuffing box has been packed or fitted with seal.

e) Cooling water is supplied to bearing—if specified.

f) Prime mover has been checked for correct direction of rotation.

g) All rotating parts are found free by turning by hand.

h) Pump is primed. Never run a pump dry.

3. RUNNING

While the pump is running, a periodic inspection should be made of:

a) Stuffing-Box

Keep stuffing-boxes (if soft packed, not fitted with mechanical seal) so that there is

sufficient leakage to lubricate the package.

b) Bearing

Check the bearing for temperature which should not exceed 70(160°F)

Grease nipples are provided for bearing lubrication.

c) Alignment

Successful operation of the pumps depends on accurate alignment. It is recommended to

re-check the alignment after preliminary run.

4. STARTING

Start the pump with discharge valve closed and bring it up to speed rapidly. When pressure is reached open discharge valve slowly. Do not operate unit for prolonged periods with closed discharge valve, so as to avoid overheating.

GHS driver, if supplied, is correctly aligned on its base plate at the factory. A certain

amount of deformation of the base plate is possible during transit and it is therefore essential

to check alignment before going into operation.

8. Grouting

A space of approximately 25mm (1’’) should be left between the base plate and top of the

foundation to be filled with grouting.
