4 INSTALLATION

Equipment operated in hazardous locations

must comply with the relevant explosion protection

regulations. See section 1.6.4,

Products used in

potentially explosive atmospheres.

Inspection prior to installation:

Six months prior to

the scheduled installation date, a Flowserve Pump

Division representative is to be employed to conduct

an inspection of the equipment and the facility. If any

deterioration of equipment is noticed, the Flowserve

Pump Division representative may require a partial or

complete dismantling of the equipment including

restoration and replacement of some components.

4.1 Location

The pump should be located to allow room for

access, ventilation, maintenance and inspection with

ample headroom for lifting and should be as close as

practicable to the supply of liquid to be pumped.

4.1.1 General installation check-list

The following checks should be made before starting

actual installation.

a) Make sure that the motor nameplate ratings and

the power supply system match correctly.

b) Check the sump depth and suction pipe length

match up.

c) Check the liquid level in the sump.

d) Check the installation equipment to be sure that it

will safely handle the pump weight and size.

e) Check all pump connections (bolts, nuts etc) for

any shipping and handling related problems.

f) Check for any evidence of lubricant leakage at

the bearings.

g) Check that the shaft rotates freely.

4.1.2 Cleaning prior to installation

Remove the rust inhibitor, flange protectors, plastic

covers, desiccant, and inspect the inside of the

pump. Repack the stuffing box and ensure that the

stuffing box drain is clear. Flush the bearings using a

hot, light oil at 82

o

to 93

o

C (180

o

to 200

o

F) while the

shaft is slowly rotated. Re-lubricate the bearings as

explained in Section 5.0

4.1.3 Manufacturer’s service

It is recommended that the services of Flowserve

Company Service Representative be employed for

installing and starting the pump as proper installation

is vital for designed functioning, performance and

reliability of the equipment.

4.1.4 Site preparation

Care should be taken to prevent an out of service

pump from freezing during cold weather. Draining

the pump is recommended when there is any

possibility of freezing.

Observe extreme caution when

priming, venting and draining hazardous liquids.

Wear protective clothing in the presence of

hazardous, caustic, volatile, flammable and hot

liquids. Do not breathe toxic vapors. Do not

swallow. Do not allow sparking, flames or hot

surfaces in the vicinity of the equipment.

4.1.5 General tools required for installation

a) Mobile crane capable of hoisting and lowering the

pump and/or motor.

b) Sets of chains, tongs and cable slings for

attaching it to the pump and motor lifting eyes.

c) General purpose hand tools, pipe wrenches, end

wrenches, socket set, screwdrivers, Allen

wrenches, wire brush, scraper and fine emery

cloth.

d) Thread sealing compound designed for stainless

steel and light machinery oil.

4.2 Part assemblies

Motors are supplied separately for MNV/MNZ pumps.

It is the responsibility of the installer to ensure that

the motor is assembled to the pump and lined up as

detailed in section 4.5.

It is also the responsibility of

the installer to take note of the pump and driver

weights for proper handling before assembly is

attempted.

4.3 Foundation

There are many methods of installing

pump units to their foundations. The correct method

depends on the size of the pump unit, its location and

limitations on its noise/vibrations. Non-compliance

with the provision of correct foundation and

installation may lead to failure of the pump and as

such, would be outside the terms of the warranty.

The foundation may consist of material that will afford

permanent, rigid support to the discharge head and

will absorb expected stresses that may be

encountered in service.

Concrete foundations should have anchor bolts

installed in sleeves that are twice the diameter of the

bolt to allow alignment and has holes in the mounting

plate as illustrated in the detail below.
