1.1
Receiving inspection
Although precaution is taken by us when packing and shipping, we urge you to carefully check
the shipment on receipt. Make sure that all parts and accessories listed on the packing list are
accounted for. Immediately report any damage or shortage to the transport company and to us.
1.2
Storage
- If the equipment is to be stored prior to installation, place it in a clean location.
- Do not remove the protective covers from the suction and discharge, which have been fastened
to keep pump internals free of debris.
- Store the pump on the motor fan cover in an upright position, or hang the pump from the cover
plate.
- Make sure to clean the pump thoroughly before installation.
1.3
Installation
- CTV pumps must be installed vertically and can be used in sumps, tanks and similar contai
-
ners.
- For a safe "outside tank" installation always consult us for arrangement of neccessary modifi
-
cations.
- Install the pump on a rigid support and fastened by the cover plate.
1.4
Piping
A pump is generally part of a piping system that can include a number of components such as
valves, fittings, filters, expansion joints, instruments, etc. The way the piping is arranged and the
positioning of the components has a great influence on operation and the operating life of the
pump. The pump cannot be used as a support for the components connected to it.
The flow of liquid from the pump must be as even as possible. It is advisable to avoid any tight
bends or drastic reductions of diameters that may cause flow resistance in the plant. In case of
diameter reduction, it is advisable to use appropriate conical reductions.
Discharge pipe
If the discharge height is more than 2 meters, a check valve shoiuld be installed in the discharge
line (see installation example, chapter 1.5)
Suction extension
Use of extension pipe is possible on CTV pumps to allow emptying from a lower level. The liquid
level can drop under the impeller (pump casing) during operation. However during startup the level
must always be over the impeller (pump casing). See installation example, chapter 1.5.
Return flow
To avoid return flow, a check valve is recommended on the discharge side as near to the pumps
as possible. It is of greatest importance in installations with high discharge height. See installation
example, chapter 1.5.
