1. GENERAL INFORMATION
Please observe the following instructions to achieve
the best pump performance possible and a trouble
free installation.
Read these instructions before installing the
pump.
Save them for future reference.
These are multistage centrifugal pumps having
more than one impeller assembled in-line. The
same flow passes through each impeller but the
pressure increases each time, i.e. more impellers,
more pressure.
The ASPRI models are manufactured to include a
recirculation system with automatic valve achieving
suction lifts of up to nine meters. By using a foot
valve on the suction pipe the pump will rapidly self-
prime when operated.
These pumps are designed to operate with clean
water, free from particles in suspension and with a
maximum temperature of 40 ºC.
Correct pump operation is assured providing
the instructions on electrical connection, ins-
tallation and use are strictly adhered to.
Failure to adhere to the instructions can
result in premature failure of the pump and
voiding of the warranty.
