5.5 Impeller-clearance setting

Importance of a proper impeller clearance

A proper impeller clearance ensures that the pump runs at high performance.

NOTICE:

Set the cold (ambient) impeller clearance according to this table. Failure to do so may result in
heat generation and equipment damage. Higher clearances are used above 93°C | 200°F to
prevent the impeller from contacting the casing due to thermal expansion.

WARNING:

•

Risk of mechanical seal damage leading to breach of containment. If a cartridge mechani-
cal seal is used, ensure that the set screws in the seal locking ring are loosened and that
the centering clips have been installed prior to clearance adjustment.

The clearance is set at 0.4mm | 0.015 in – 0.5mm | 0.020 in depending on pump size and impeller con-
figuration at the factory but could change due to piping attachment during installation. A change in pump
performance may be noted over time by a drop in head or flow or an increase in power required.

Impeller clearance methods

You can set the impeller clearance with either of these methods:

•

Dial indicator method

•

Feeler gauge method

5.5.1 Set the impeller clearance - dial indicator method

WARNING:

Failure to disconnect and lock out driver power may result in serious physical injury or death.
Always disconnect and lock out power to the driver before performing any installation or main-
tenance tasks.

•

Electrical connections must be made by certified electricians in compliance with all inter-
national, national, state, and local rules.

•

Refer to driver/coupling/gear manufacturer's installation and operation manuals (IOM) for
specific instructions and recommendations.

1.

Remove the coupling guard.

2.

Set the indicator so that the button contacts either the shaft end or the face of the coupling.

3.

Loosen the jam nuts (423B) on the jack bolts (371A), and then back the bolts out about two turns.

4.

Tighten the locking bolts evenly (370C), bringing the bearing housing (134A) towards the frame
(228) until the impeller contacts the casing.

5.

Turn the shaft to ensure that there is contact between the impeller and the sideplate or wear ring.

6.

Set the indicator to zero and loosen the locking bolt (370C) about one turn.

7.

Thread in the jack bolts (371A) until the jack bolts evenly contact the bearing frame.

8.

Tighten the jack bolts evenly about one flat at a time, moving the bearing housing (134A) away from
the bearing frame until the indicator shows the correct clearance.
Refer to the impeller clearance table to determine the correct clearance.

9.

Tighten the bolts evenly in this order:

a) Tighten the locking bolts (370C).
