VersaFlo UP, UPS
Construction, VersaFlo UP, UPS
The VersaFlo UP, UPS 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 prob-
lems in connection with disposal have been omitted.
The pump features:
• Motor with three speeds. (UPS models)
• Dual voltage motor. (UP models)
• Ceramic radial bearings.
• Carbon thrust bearing.
• Stainless steel rotor can, bearing plate and rotor clad-
ding.
• Stator housing in aluminium alloy.
• Cast iron or bronze pump housing.
• Stator with built-in thermal overload switch.

Pump
In-line cast iron and bronze spiral pump housing.
Flange dimensions for USA are according to individual
submittal data the flanges have ¼ NPT pressure gauge
tappings. Tapped holes are provided on the underside of
the pumps. These holes can be used for fitting the pump
to a base plate or bracket by means of hexagon screws.
The pump housing is provided with a replaceable stain-
less steel/Teflon neck ring. The ring reduces to a
minimum the amount of liquid running from the
discharge side of the impeller to the suction side.
Impeller
The impeller is made of stainless steel, AISI 304 SS.
As the impeller is made of stainless steel sheet, it can
be pressed into the correct hydraulic form.
Installation
VersaFlo UP, UPS pumps can be installed in horizontal
and vertical pipes.
Note: The motor must never point downwards.
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.
In humid locations, a drain hole in the motor must be
opened. The drain hole must always point downwards.
