DESCRIPTION The pumps of serie AS are centrifugal side channel self-priming with star-shaped impeller; the ports are located on the longitudinal axe with the suction located on the front of the pump cover. All models have threaded connections for fittings according to DIN 11851 standard (unless otherwise requested). -

INSTALLATION SUCTION AND INFLOW CONDITIONS (NPSH = Net Positive Suction Head) NPSH of system (available NPSH) In order to ensure that pump operation is free from cavitation, it is essential to observe the maximum permitted suction lift ha geo max or the minimum allowable head hc geo min. NPSH of pump (required NPSH) The centrifugal pumps can operate correctly only if vapour has not formed inside. -

Lower Higher voltage voltage Pict C.S.F. Inox S.p.A. will accept no responsibility for damage to property and/or injury to persons caused by failure to comply with technical standards and regulations in force. NON-PERMITTED USES Do not use the pump with a suction pressure greater than the specified value (0.5 times the discharge head generated by the pump). -

Insufficient flow - Increased system back pressure on discharge side; increase piping diameter. - Air entering mechanical seal; check its condition. - Viscosity of fluid greater than that specified in the order. Contact manufacturer. - Clearances between impeller/cover and impeller/body have increased. Check and correct. Loss of head - Back pressure on discharge side has fallen;... - Page 11 SEALS All C.S.F. centrifugal pumps of the AS series are fitted with unified mechanical seals according to EN 12756 - ISO 3069 standards, in order to grant the interchangeability (subject to verification of axial space). The type of mechanical seal and material are chosen according to the liquid to be pumped.
- Page 12 EXECUTION Q COMPACT DOUBLE MECHANICAL SEAL ASSEMBLY “Q” Double back-to-back assembly seal, suitable for abrasive, dirty, crystallizing or high-temperature liquids. The seal assembly is completely housed and the latter is provided with inlet/outlet flushing media that lubricates and cools the seal faces preventing also crystal formation.

F= Turn it over to access the screws (26) which allow you to separate the pump casing (1) from the support (5). Extract the fixed part (6) of the seal from the pump casing. G= Unscrew the screws (45-27) to remove the shroud eccentric (43) and the bearing cover (8) from the support (5). - Page 15 13.2 DISASSEMBLY OF AS PUMP ''Q'' EXEC. Refer to the "T" exec. (paragraph 13.1) for the A-B-C-D phases E= Pump casing disassembly (1). Unscrew the flushing pipes (71), remove the screws (68) and pull back the mechanical seal cover (60). Extract the support/pump casing (26) fixing screws and separate them (1-5).
- Page 16 BEARINGS MAINTENANCE 14.1 BEARINGS MAINTENANCE FOR AS SERIES PUMPS In AS series pumps up to motor size 132 (5.5 ÷ 9.2 kW) the bearings installed are shielded and consequently do not need to be lubricated. 14.2 BEARINGS MAINTENANCE FOR AS SERIES PUMPS WITH HOUSING SIZE 160 - 180 The bearings of AS pumps are sized for an operational life of 20,000 hours or more.

Page 17: Cleaning Procedure
CLEANING PROCEDURE The cleaning of stainless steel pumps depends on the process liquid. Typically the cleaning process should be developed by a plant responsible of sanitization. C.S.F. Inox recommends a fluid velocity between 1,5-3 m/s, with rinsing water and chemical agent like alkaline detergent and acid. - Page 20 Distributed in the UK by..Pump Engineering Limited.
