Page 5: Description
DESCRIPTION The CS series comprises single-stage centrifugal pumps with axial suction port, open centrifugal impeller and trapezoidal volute casing. All models have threaded connections for fittings according to DIN 11851 standards (unless otherwise requested) and all models are fitted with mechanical seals. The materials used for the components and the mechanical seal are chosen according to the liquid to be pumped. -
Page 6: Sound Pressure Level
SOUND PRESSURE LEVEL The sound pressure level of centrifugal pumps is the following (see table): Pump type CS 25-145 4-poles CS 25-175 4-poles CS 32-110 4-poles CS 32-145 4-poles CS 32-175 4-poles CS 32-210 4-poles CS 32-260 4-poles CS 40-145... - Page 7 2. RADIAL ALlGNMENT The radial alignment is controlled with a rule or a dial indicator or laser. By resting the rule on the periphery of the hubs and matching up two opposite teeth, you will have a sufficiently broad line of contact to check they match up throughout their surface area. Better alignment precision is obtained with the help of a dial indicator or laser (keep to radial tolerance Y). 3.

Page 9: Suction And Inflow Conditions
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. -
Page 10: Electrical Connection
For this reason, when sucking from a tank located at a lower level, the pipe must reach below the free surface of the liquid. In order to prevent the formation of vortices and avoid the risk of sucking in air, always keep a minimum head at the pipe inlet (h. min.) equal to at least the dynamic head plus a safety margin of 0.1 m (Fig.2). -
Page 11: Operation
OPERATION 10.1 PRELIMINARY OPERATIONS - Check that the pump turns freely under hand pressure. - Check that the clamp joining the pump casing and the lantern bracket is well tightened and that it cannot be easily unscrewed by hand. The tightening of the clamp must be carried out by means of a spanner and NOT by hand. -

WORKING IRREGULARITIES We are herewith listing some of the possible working irregularities which may occur using the pumps, with a table helping to find out the possible causes and how to solve the problem. Trouble: A) The pump does not run B) The delivery is not sufficient C) The pressure is not sufficient D) The pump stops priming E) Power absorption too high F) Leakages from the mechanical seal G) Short life of the mechanical seal H) Failure of the mechanical seal I) Anomalous vibrations and/or noise... - Page 14 TROUBLE p. 14...

23) Voltage not suitable for the installed motor. - Replace the motor with one having a suitable voltage. 24) Mechanical seal worn. - Replace the mechanical seal. 25) Pump fluid or temperature not suitable for the assembled mechanical seal or its parts. - Verify the mechanical seal selection. 26) Non-cleaning when using fluids which tend to crystallize. - Increase washing cycles and don’t leave the product inside the pump for a long time. 27) Misassembly of the mechanical seal. -

SINGLE MECHANICAL SEALS - CS / CSX / CSK EXECUTION T / W STANDARD MECHANICAL SEAL “T” Standard execution foresees the assembly of an submerged internal mechanical seal on the product, housed behind the impeller in a specific tapered chamber so as to guarantee correct lubrication conditions. MECHANICAL SEAL WITH CIRCULATION "W" Internal mechanical seal with circulation forced by the pumped liquid. -
Page 17: Double Mechanical Seals - Cs / Csx
DOUBLE MECHANICAL SEALS - CS / CSX / EXECUTION Q COMPACT DOUBLE MECHANICAL SEAL “Q” Double mechanical seal with circulation of washing and cooling liquid. The function of flushing is that of cleaning, lubricating and cooling the seal; the liquid in circulation must be clean. If the seal is leaking, the flushing liquid will point out this fault. - Page 18 "Q" and "V" Exec. mechanical seal auxiliary flushing Upon the first start up, the filling of the pump, must be guaranteed. Furthermore, you must guarantee the full filling of the auxiliary systems, if present, such as the lubrication circuit of the external dual- seal (seal execution “Q”) or the external flushing circuit (seal execution “V”). Lack of compliance with the present requirements causes the dry operation of the pump and of the mechanical seal; consequently the mechanical seal can be overheated and damaged. The auxiliary services (optional) are the following: - flushing for the double external mechanical seal (seal execution “Q”) - external flushing for the internal seal (execution “V”).

Page 23: Bearings Maintenance
BEARINGS MAINTENANCE 20.1 BEARINGS MAINTENANCE FOR CS SERIES PUMPS In CS 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. 20.2 BEARINGS MAINTENANCE FOR CS - CSX SERIES PUMPS WITH HOUSING SIZE 160 ÷ 200 The bearings of CS pumps are sized for an operational life of 20,000 hours or more. -
Page 24: Bearings Maintenance For Csk Series Pumps
20.3 BEARINGS MAINTENANCE FOR CSK SERIES PUMPS The bearings of the pump support are lubricated using the oil bath method. The pump is supplied with the support without oil; fill the support before starting the pump, using oil supplied by C.S.F., or an equivalent type of oil. The procedure to fill with oil is the following: with the pump off, unscrew the release plug (pos. 74) and turn the bulb of the constant level oiler (pos. 76), as shown in the figure, then pour the oil through the release plug until it reaches the level of the hole at the side where the constant level oil-feeder is situated, as shown in the figure; then partially fill the bulb as a reserve and turn it to the closed position and screw the release plug back on. - Page 25 Remove the covers of the front and rear bearing (12) with seal rings (32) and gaskets (77). Remove the shaft (4) from the support (6). Complete the disassembly by remo- ving the bearings (8-9) and Speedi sleeve rings (125) from the shaft (4). 20.5 ASSEMBLY Perform the disassembly steps in inverse order to assemble the...
- Page 26 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. Chemicals like hypochlorite and chlorine must be avoided because stainless steel could be damaged by corrosion.
