Notes: N/A = Not applicable.
1) The standard grease used on TECO motor frames 90, 100 and 112 is unsuitable as it does not generate sufficient lubricating film

thickness with the relatively low viscosity 5K grease. The alternative grease 2A is acceptable and must be specified.

2) Standard ALPAK motor frames 80 to 132 inclusive have bearings at the non-drive end with a special retention device. This device is not

acceptable for use with the Mark 3 ISO Close Coupled unit. The ALPAK machine with bearing cap locating the drive end bearing is
acceptable.



A wide range of electric motors have been tested and
approved for use with Mark 3 ISO Close Coupled
units. The table lists acceptable motors and indicates
whether the standard motors are approved or if a
modification is required.

The position of the terminal box can be changed by
rotating the complete motor. To do this on motor frames
80 and 90, remove the fasteners from the motor flange,
rotate the motor and re-fit the fasteners. For motor
frames 100 and above, with multi-positioned feet, also
unbolt the feet and refit in the appropriate position.

3.3.9 Accessories
Accessories may be fitted when specified by the
customer.

3.4 Performance and operating limits

This product has been selected to meet the
specifications of the purchase order. See section 1.5.

The following data is included as additional
information to help with your installation. It is typical,
and factors such as temperature, materials, and seal
type may influence this data. If required, a definitive
statement for your particular application can be
obtained from Flowserve.

3.4.1 Operating limits

3.4.1.1 Temperature limits of working fluids
Horizontal units: -20 ºC (-4 ºF) to +160

ºC (320 ºF).

Vertical units: -20 ºC (-4 ºF) to +120 ºC (248 ºF).
(These limits subject to approved mechanical seal
area design.)

3.4.1.2 Ambient temperature
These units are normally fitted with TEFC motors
suitable for an ambient temperature up to 40 ºC
(104 ºF). Specific pumps may be fitted with motors to
suit client's requirements with other ambient
temperature limits - see motor nameplate for details.

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.

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. Refer
to the general arrangement drawing for the pump set.
