TP80-240/2 Products Guide

General data
VersaFlo® TP

The pumps must be installed in such a way that strain
from the pipework is not transferred to the pump
housing.
The pump may be suspended direct in the pipes,
provided the pipework can support the pump. If not, the
pump must be installed on a mounting bracket or base
plate.
Space requirements
For inspection and motor/pump head removal a 12"
(300 mm) clearance above the motor is required.

Pumped liquids
Thin, clean, non-aggressive and non-explosive liquids,
not containing solid particles or fibers that may
mechanically or chemically attack the pump, please
see “List of pumped liquids" below.
Examples of liquids:
• central heating system water (we recommend that
the water meets the requirements of accepted
standards on water quality in heating systems)
• cooling liquids
• domestic hot water
• industrial liquids
• softened water.
If glycol or another antifreeze agent is added to the
pumped liquid, the pump must have a shaft seal of
the type RUUE.
The pumping of liquids with densities or kinematic
viscosities higher than those of water can cause
• a considerable pressure drop
• a drop in the hydraulic performance
• a rise in the power consumption.
In these situations, equip the pump with an oversize
motor. If in doubt, contact Grundfos.
If the water contains mineral oils or chemicals, or if
other liquids than water are pumped, the O-rings should
be chosen accordingly.
Liquid temperature
Liquid temperature: –13°F to +284°F.
Please note that shaft seals operating close to their
maximum temperature will require regular
maintenance, i.e. replacement.
List of pumped liquids
Grundfos TP pumps are designed for circulation
systems with constant flow, TPE pumps for systems
with variable flow.
Thanks to their design, these pumps can be used in a
wider liquid temperature range than pumps of the
canned rotor type.
A number of typical liquids are listed page 10.
Other pump versions may be used, but we consider the
ones stated in the list to be the best choices.
The list is intended as a general guide only, and it
cannot replace actual testing of the pumped liquids and
pump materials under specific working conditions. If in
doubt, contact Grundfos.
However, use the list with some caution as factors such
as
• concentration of the pumped liquid
• liquid temperature or
• pressure
may affect the chemical resistance of a specific pump
version.

A
May contain additives or impurities that may cause shaft
seal problems.
B
The density and/or viscosity differ from those of water.
Consider this when calculating motor and pump perform-
ance.
C The liquid must be oxygen-free (anaerobic).
D Risk of christallization/precipitation in shaft seal.
E Insoluble in water.
F
The shaft seal rubber parts must be replaced with
FKM rubber.
G Bronze housing/impeller required.
H Risk of formation of ice on the standby pump.
