BJZ SERIES STAINLESS
STEEL SELF-PRIMING JET PUMP
INSTRUCTION MANUAL
1.Specification
This manual has been conceived to offer the adequate information on the installation, operation and maintenance of our
electro pumps. We suggest you read it thoroughly. These are centrifugal horizontal electro pumps with self-priming capacity
and supplied with century system so to reach suctions of up to 9 mts. Connect a foot valve and the pump will get an im-
0
mediately self-priming.They have been designed to operate with clean water at a maximum temper-ature of 45 C.
Operating with any kind of water, other than that just described should be avoided. These pumps have been built with
first quality materials which submitted to strict hydraulic and electric controls and verified thoroughly.
Following these present instructions and the electrical chart, will help you to achieve a correct installation. If failure to do
this could result in motor overcharge and any other consequences, which we wish to be relieved of.
2.Installation
The electric pumps must be placed as possible to the water level in order to obtain the minimum suction lift and
reduce the loss of head. If the installation is be permanent. pump should be attached to the floor or ground using
the holes pump bracket.
They should be installed in dry place and safe form any possible flooding.
3.Pipe assembly
The suction pipe must be resistant to depression and be kept submerged 30 cms below water level to prevent the formation
of whirs and its inscrutability consequence: Air leaks if suction lift is over 7 mts. the use of a pipe of a bigger diameter than
the admission port of the pump is recommended. the unions or connections must be absolutely water-tight. It is recom-
mended to reduce pipe bends to the minimum inclination of 2%. The discharge pipe should have a diameter equal or
bigger than of the pump outlet. In any case should the suction or discharge pipes rest on top of the pump.

Possible faults causes and solutions
Overall dimension
4.Electrical connection
The electric installation should be provided by a system of multiple separations with contact openings of at
least 3 mm.
The protection of the system will be made by a differential switch (1fn=30mA.) The electric cable must
correspond to the EEC(2) norm or to the type H07 RN-F according to VDE 0250.
The single phase motors have a built-in thermal protection.
Look at the schematic drawing on Fig(1) for a correct electrical connection.
5.Controls prior to the initial starting
Check that the tension and frequency of the electric supply correspond to that indicated on the technical
characteristics label.
Make sure that the shaft rotates freely.
Fill pump body with water, unscrewing slightly the priming plug.
Verify the motor sense of rotating as indicated on the fan cover.
THIS PUMP SHOULD NEVER BE DRYOPERATED.
6.Starting
Open all gate valves installed in the suction and connect the electric supply switch and wait for the priming
to be completed. If a foot valve has been installed. the priming will be instantaneous.
If motor fails to start or does not deliver water.
Refer to our trouble Shooting list with the possible problems and consequent actions to take. This
information will be found on the next pages.
7.Maintenance
Our electro pumps do not need any special maintenance.
Pump body should be drained during periods of low temperatures or long period of inactivity. If this inactivity
last longer, pump should be cleaned and kept in a dry and aired place.
