11.0 - OPERATION 11.1 - PRELIMINARY OPERATIONS BEFORE START-UP - Check that the pump turns freely under hand pressure - The clamp joining the pump casing and the lantern bracket must be well tightened and it should not be easily unscrewed by hand. The clamp must be tightened using a wrench and NOT simply by hand. -
Page 21: Cleaning The Pump
- The pump must operate smoothly and without vibrations. - Do not operate without liquid and in any case avoid prolonged operation with the discharge gate valve closed. - Check that the suction liquid level is always sufficient to grant an adequate energy load for normal operation of the pump. -

Page 26: Seals
14.0 - SEALS All CSF Inox CS series pumps are fitted with mechanical seals with standardized seats in compliance with standards EN12756 and ISO 3069. The type of mechanical seal and material are chosen according to the liquid to be pumped. -
Page 27: Double Mechanical Seals - Cs / Csx
EXECUTION Y EXTERNAL MECHANICAL SEAL “Y” For all cases where the mechanical seal must not touch the pumped product, in order to avoid sanitary problems, corrosion and conditioning of its running. EXECUTION V INTERNAL MECHANICAL SEAL “V” The external liquid circulation chamber creates a protective barrier inthe presence of aggressive or toxic liquids. -
Page 28: Double Mechanical Seals - Csk
14.3 - DOUBLE MECHANICAL SEALS - CSK EXECUTION Q DOUBLE MECHANICAL SEAL “Q” Double mechanical seal (back-to-back) with liquid circulation. 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 29 Exec."Q": in case of leaks from the process seal (pump side) the flushing liquid comes into contact with the pump fluid; always use a flushing liquid that is compatible with the process liquid. The flushing must be arranged with a pressure value of 0,5 ÷ 1 Bar higher than the pressure foreseen at the suction, in order to have the right compensation.
