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.
