3. Technical data 3.1 Operation condition Delivery liquids : non-viscous, non-flammable/explosive, not containing solid or fiber particles, and should not cause physical nor chemical damage to the pump. For viscosity larger than water, use pumps with a higher output if necessary. Whether a pump is suitable for a certain liquid depends on factors such as the liquid’s chlorine content, PH value, temperature and composition, among other factors. - Page 5 3.4 Minimum Inlet Pressure, NPSH Check the minimum inlet pressure under the following conditions: •The liquid temperature is high •Flow rate significantly larger than quoted maximum •The fluid requires a long sucking distance •Long pipes lead to the fluid inlet point Use the formula below to calculate the maximum suction distance of the pump: H = Pb x 10.2 –...

Page 6: Maximum Inlet Pressure
3.5 Maximum inlet pressure The following table shows the maximum permissible inlet pressure. However, the actual inlet pressure plus the pressure against a closed valve must always be lower than the maximum permissible operating pressure. If the maximum permissible operating pressure is exceeded, the conical bearing in the motor may be damaged and the life of the shaft seal reduced. -

4. Installation 4.1 The pump must be secured to a horizontal, plane and solid foundation by bolts through the holes in the base plate. When installing the pump, follow the procedure below in order to avoid damaging the pump. Step Action Arrows on the pump base show the direction of flow of liquid through the pump. -

5. Electrical Connection 5.1 The electrical connections must be performed by a qualified electrician in compliance with the required regulations. 5.2 Make sure that the supply voltages and frequencies matched with the electric motor rating plate. Provide suitable general protection against short circuits on the power line. 5.3 Before removing the terminal box cover and before any removal/dismantling of the pump, make sure that the electricity supply has been switched off. - Page 9 Start-up close open water flow 1.

Page 11: Maintenance
7. Maintenance Before starting work on the pump, make sure that all power supplies to the pump have been switched off and that they cannot be accidentally switched on. Pump bearings and shaft seal are maintenance-free. Motor bearings Motors not fitted with grease nipples are maintenance-free. Motors fitted with grease nipples should be lubricated with a high temperature, lithium-based grease. -
