General data

Terminal box modules

UPS pumps are equipped with a standard or protection
module in the terminal box. Pumps with standard mod­ule must be connected to the mains via an external con­tactor, whereas pumps with protection module can be
connected directly to the mains.

For further information about the different modules, see
pages 20 through 21.

Applications

The pumps are designed for circulation of liquids in
heating and air-conditioning systems. They can also be
used in domestic hot-water systems.

To ensure optimum operation, the dimensioning range
of the system must fall within the performance range of
the pump. See data sheets.

VersaFlo® UP, UPS

Pumped liquids

Thin, clean, non-aggressive and non-explosive liquids,
not containing any solid particles, fiber or mineral oil.

In domestic hot-water systems it is advisable to use
bronze pumps only for water with a degree of hardness
lower than approx. 14°dH. For water with a higher
degree of hardness a TP dry-rotor pump is recom­mended.

The pumps must not be used for the transfer of inflam­mable liquids such as diesel oil and pe trol.

Liquid temperature, see section Temperature limits on
page 15.

UP(S) Series 200 pumps are of the canned rotor type,
i.e. pump and motor form an integral unit without shaft
seal and with only two gaskets for sealing. The bear­ings are lubricated by the pumped liquid.

Attention has been focused on using as few materials
as possible, and the use of materials that might cause
problems in connection with disposal have been omit­ted.

Features:

• UPS motors are two- or three-speed motors.
UP motors are single-speed dual-voltage motors.

• Stainless steel rotor can, bearing plate and rotor
cladding.

• Stator housing in aluminum alloy.

• Cast iron or bronze pump housing.

• Stator with built-in thermal overload switch.

Motor

The motor, pos. 4, is a 2- or 4-pole, asynchronous
squirrel-cage motor. As the motor is cooled by the
pumped liquid, the noise level is very low.

Stator housing

Pressure die-cast aluminum stator housing can be
turned to change the position of the terminal box.

The stator housing has eight drain holes to enable con­densed water to escape. The vent hole under the termi­nal box allows the water to evaporate from the stator.
The drain holes must point downwards.

The permissible terminal box positions are shown in the
drawing below. The positions apply to both vertical and
horizontal mounting.

TM02 1398 1101TM03 2260 4005

Fig. 4 Possible terminal box positi ons

Note: The terminal box must only be turned to the

above positions.
The drawing below shows the standard box position.

Rotor can

The rotor can, pos. 7, is made of drawn steel sheet and
fitted with an inspection screw directly at the top.

There is an O-ring seal between the inspection screw
and the rotor can. For reasons of safety, the hole for the
inspection screw will deflect a possible jet of liquid if the
inspection screw is removed.

The outer radial bearing is fitted into the top of the rotor
can.

Shaft with rotor

The shaft, pos. 8, is made of stainless steel and
equipped with two tungsten carbide bearings.

To further improve the internal circulation of the
pumped liquid in the rotor can, the shaft of 4-pole
motors is fitted with a small rotor impeller.

The rotor is made of soft-annealed iron lamination and
provided with copper or brass bars. The short-circuit
rings are made of copper.

The rotor is encapsulated in a thin stainless steel clad­ding and dynamically balanced.

The thrust bearing is secured to the shaft in a sphe ri­cally flexible suspension.

Fig. 5 Standard terminal box position

The nameplate can be turned in steps of 45°.
The positions of the terminal box and the nameplate are

changed as described above.
The stator wires are self-bonding. The wires and the

terminal box are connected by a terminal plug.
The stator incorporates a thermal overload switch for

protection of the motor if the winding temperature
becomes too high.

Bearing plate

The bearing plate, pos. 10, is made of stainless steel.
The inner radial bearing is pressed into the bearing

plate, ground and honed. The relatively large bearing
plate surface means that motor heat is effectively car­ried away by the pumped liquid.

Impeller

The stainless steel impeller, pos. 13, is of the radial
type with curved blades. It is secured to the shaft by a
split cone and nut (left-hand thread).

Pump housing

The pump housing, pos. 16, is available in cast iron or
bronze. All pump housings are flanged for the individual
markets. See also Product range concerning flanges
and Product numbers concerning port-to-port lengths.

The pump housing is of the in-line type. A stainless
steel/PTFE neck ring minimizes the recirculation and
improves pump efficiency.

The bottom of the housing has threaded holes for fas­tening to a base plate.

Pumped liquids

CAUTION: This pump is intended for use with water

only.
Your VersaFlo UP(S) pump can be used to circulate

• potable hot water

• water for hydronic heating

• cooling water.
In domestic hot-water systems it is advisable to use

a bronze pump (VersaFlo UP(S) model) only for water
with a degree of hardness lower than 14 grains per gal­lon of hardness. For water with a higher degree of hard­ness, a direct coupled VersaFlo TP pump is recom­mended.

If the pump is installed in a heating system, the water
should meet the requirements of accepted standards
on water quality in heating systems.

The pump is lubricated and cooled by the liquid being
pumped. Therefore, the pumped liquid must always be
allowed to circulate through the pump. Extended peri­ods without circulation will cause premature wear to the
bearings and excessive motor heat. The pumped liquid
must also meet the following requirements.

The pumping of liquids with densities or kinematic vis­cosities higher than those of water will cause

- a considerable pressure drop

Inlet pressure

To avoid cavitation noise, the following minimum pres­sures are required at the pump suction flange:

protection.

Pumps with standard module

For motor protection the contactor is to be connected to
the pump’s built-in thermal overload switch to protect
the pump against overheating at all three speeds.

Standard module indicator lights

The indicator lights on pumps with standard module
show whether the pump is live, or whether the phase
sequence of three-phase pumps is wrong.

• Even if the red indicator light is on, the pump is op­erating normally.

• Pumps fitted with other modules than the standard
module must not be connected to a frequency con­verter.

• Depending on the frequency converter type, this
may cause increased acoustic noise from the motor.
Furthermore, it may cause the motor to be exposed
to detrimental voltage peaks.

• The motor must be protected against voltage peaks
higher than 650 V between the motor terminals.

Acoustic noise and detrimental voltage peaks can be
reduced by fitting an LC filter between the frequency
converter and the motor.

Pumps with relay module

The relay module is available for UPS pumps as an
option for 1 x 115/230 V and 3 x 208-230 V units.

The module enables direct connection of the pump to
an external mains switch. Furthermore, the module has
a signal output for external operating or fault indication.
By means of a selector switch the output can be set to
activation during operation or fault.

The pump is connected directly to the mains as the
pump incorporates overload protection at all three
speeds.

Note: Pumps with relay module must not be connected
to a frequency converter.

If the pump has been cut out by the thermal overload
switch, it will restart automatically when it has cooled to
normal temperature, provided the external on/off con­tact is closed.

Note: If the thermal overload switch has cut out the
pump three times within a short time, the relay must be
reset manually by switching off the electricity supply.

Relay module indicator lights

The relay module indicator lights provides detailed
operating and fault indications.

All pumps with relay module incorporate a green and a
red indicator light. Functions, see table in Signal output
