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.

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.

Allow sufficient room to facilitate the back pull-out

feature on V-belt driven units.

Refer to the general arrangement drawing for the

pump set.

4.2 Part assemblies

Motors may be supplied loose on MARK 3 pumps,

typically on frame sizes 400 and above. It is the

responsibility of the installer to ensure that the motor

is assembled to the pump and lined up as detailed in

section 4.5.2.

4.3 Foundation

The foundation may consist of any

material that will afford permanent, rigid support to

the full area of the pump or driver supporting

member. It should be of sufficient size and mass to

absorb expected strains and shocks that may be

encountered in service. Concrete foundations built

on solid ground are desirable. Use a concrete grade

with a strength of approximately 20MPa (2900 PSI).

The purpose of foundation bolts is to anchor the

pump unit securely to the foundation such that the

foundation and pump assembly become a single

structural unit. High strength steel foundation bolts

(SAE Gr. 5 or equal) of the specified diameter should

be located according to the elevation drawing

provided. Each bolt should be surrounded by a pipe

sleeve which is two or three times the diameter of the

bolt. The sleeves should be securely anchored and

designed to allow the bolts to be moved to conform

with the holes in the baseplate. The bolts should be

sufficiently long to allow for wedges or shims or

levelling nuts under the baseplate, and a washer,

heavy hex nut and hex jam nut for retention. Since

baseplate levelling is performed after the foundation

has cured, it is best to use extra long bolts that can

be shortened after the installation is complete.

4.4 Baseplate installation

Position the baseplate and pump next to the

foundation and clean the foundation surface

thoroughly. Remove the rag packing from the pipe

sleeves and place wedges or ships as close to the

foundation bolts as possible. These may be omitted

if a jacking nut on the foundation anchor bolts is

preferred for levelling.

Remove the flange covers and check inside the

pump nozzles for cleanliness. Kerosene is

recommended as the best solvent for removing

factory applied rust preventative. Ensure that all

traces of rust preventative are removed from the

discharge and suction flange faces, the exposed

shafting and all coupling surfaces. Flush the pump

internals of any rust preventative applied for long-

term storage.

Lift the baseplate assembly, remove the shipping

skids and clean the underside of the baseplate.

Position the baseplate over the foundation and lower

the unit over the foundation bolts and onto the

wedges, shims or jacking nuts.

a) Level the pump baseplate assembly. If the

baseplate has machined coplanar mounting

surfaces, these machined surfaces are to be

referenced when leveling the baseplate. This

may require that the pump and motor be

removed from the baseplate in order to reference

the machined faces. If the baseplate is without

machined coplanar mounting surfaces, the pump

and motor are to be left on the baseplate. The

proper surfaces to reference when leveling the

pump baseplate assembly are the pump suction

and discharge flanges. DO NOT stress the

baseplate.

b) Do not bolt the suction or discharge flanges of

the pump to the piping until the baseplate

foundation is completely installed. If equipped,

use leveling jackscrews to level the baseplate. If
