SXA HIGH EFFICIENCY END-SUCTION CENTRIFUGAL PUMP

CONFORMS TO DIN24255, BS EN733 and ISO9908

General description

InfinityFlo SXA series single stage end-suction centrifugal pumps are based on the latest technology. The pump

design is based on the latest technology and long term experiance of the African market requirements.

The volute is an end-suction and radial discharge design. The discharge centerline and shaft are on the same vertical

plane. The mounting design is to international standards where feet on the volute are bolted directly to the base.

The pump has a back-pull-out design, which allows disassembly and maintenance of the rotating assembly

without disturbing the pipework or motor.

The bearing frame is supplied with two ball bearings. Standard lubrication is greased for life bearings with oil as an

option..

The volute, together with flanges and feet are one integral casting.

The pump complies with DIN24255 and BS EN733 standard, they have a high degree of interchangeability.

Motor selection Selected motor shall have power ratings, excluding the service factor ( if any), at least equal to the absorbed power

plus the safety factor stipluated in the table below.

Never allow the absorbed power at duty point to exceed the motor rated output.

≥22 ~ 55 ≥30 ~ 75 115

For higher ambient temperatures and / or site altitudes higher than 1000 m above seal level, the specified motor

output must be derated by using the factor KHT. The results in an admissible output (Padm) of the motor:

Padm = Prated x KHT

Noise According to ISO 3746

Attention must be given to the exposure of personnel to the noise, and local legislation will define when guidance to

personnel on noise limitation in required, and when noise exposure reduction is mandatory. This is typically 80 to 85

dBA.

The usual approach is to control the exposure time to the noise or to enclose the machine to reduce emitted sound.

You may have already specified a limiting noise level when the equipment was ordered, however if no noise

requirement were defined, then attention is drawn to the following table to given an indication of equipment noise level

so that you can take the appropriate action in your plant.

Pump noise level is dependent on a number of operational factors, flow rate, pipework design and acoustic

characteristics of the building, and so the values given are subject to a 3 dBA tolerance and cannot be guaranteed.
