A:
GENERAL
Taco GT pumps are single stage double suction axially split
pumps supplied either bare shaft or complete with an electric
motor. Details of the pump type and model, serial number and
operating data are indicated on the pump nameplate.
The pump must be installed and operated in full compliance with
these instructions. The pump may not be operated outside the lim-
its specified on the nameplate and within this manual. The pump
should only be operated by skilled trained personnel. The manu-
facturer will not accept liability if these instructions are not fol-
lowed. This manual does not take into account any specific local
regulations or bylaws that may be applicable, and it is the respon-
sibility of the installer to ensure compliance with such regulations.
A1: Application
Taco GT pumps are suitable for continuous pumping of clean
water and liquids with properties similar to water, with fine solids
content not exceeding 200 ppm.
A2: Area of Operation
May be installed within a building or externally. Wherever
installed, protect the pump from frost, snow and flooding. Care
must be taken to ensure that cold weather will not cause the
pump or pipes to freeze, and installers may wish to consider lag-
ging or trace heating.

A3: Spare Parts
Spare parts are available from Taco distributors which can be
located at www.taco-hvac.com. Please quote the pump model
and serial number for all spares enquiries.
The pump user is strongly recommended to carry replacement
spares for parts which are wearing items:
• Mechanical seal or gland packing
• Casing wear ring
• Shaft sleeve
• Casing gasket
• Gland plate gasket
Only genuine Taco spare parts should be fitted. Use of other
parts will invalidate the manufacturer's warranty and liability for
consequential damage.
A4: Transport
The pumpset must remain horizontal during transport and lifting.
Only use certified lifting equipment suitably rated for the weights
to be lifted.
When hoisting the bareshaft pump only, secure a sling of suitable
load capacity around the suction flange and bearing housing as
indicated (see Figure 1). For new installations, keep the pump on
its original pallet while moving around site or on transport. If the
original pallet is not available, the pump should be securely bolted
to a pallet of generous size to ensure stability.
Figure 1: Attaching a Sling to the Pumpset
Lifting the complete pumpset (pump, motor and bedplate) may
be carried out using a forklift or with a set of lifting chains secured
to the lifting points provided on the bedplate (see Figure 2).
