Page 3: General Information
The intermediate adaptor has got a very sturdy construction and is entirely composed of a technopolymer (MSP-E) or cast iron (MSP-N). lt has been specially designed to keep the electric motor in a distance from the rest of the pump and to contain the containment shell and the external magnetic coupling. -
Page 4: Internal Magnetic Core
SiC. BASE The base which supports the motor is of bent lamination of stainless steel according to AISI 304 (MSP-E). The MSP-N pumps mount intermediate adaptors of cast iron, equipped with feet, which support both the pumping unit and the motor by lifting them from the control base. -

PRE - INSTALLATION PACKING The structure of the packing and the employed materials are chosen according to shape, dimensions and weight of the machine, which has to be shipped. We may adopt solutions of the following type: Cardboard box with filling material for machines of small dimensions; Cardboard box and wooden pallet with filling material for bigger pumps;... -
Page 6: Installation
INSTALLATION POSITIONING OF THE MACHINE The pump has to be mounted in the best possible position to assure An easy installation of the suction and delivery tubes. The machine should be positioned in immediate neighbourhood of the suction column or tank. Elbows and contractions should be excluded as far as possible. -
Page 7: Connection Over Head
CONNECTION OVER HEAD (Fig. 1 ) The pumps of this series have been designed above all for installation as shown in figure 1. Connection of the suction piping always requires a horizontal section as short as possible and a maximum distance of 4 metres between the delivery port and free liquid surface. It is advisable to install a filter (do not mount the foot valve) at the end of the suction manifold if the liquid contains impurities. -
Page 8: Movable Connection Carriage
MOVABLE CONNECTION ON CARRIAGE As far as the safety of the operator reliability, performances and life are concerned the use of the self- priming centrifugal pump with magnetic drive mounted on a carriage certainly is the less suitable operating solution. The customer should be familiar with the limits of operation, which should be carefully observed during this kind of use. -
Page 9: Control Instruments
CONTROL INSTRUMENTS To guarantee a correct functioning the machine should be equipped with instruments, which control every instant of its operation, for example.: A manual vacuum gauge installed on the rectilinear tract of the suction tube in the immediate neighbourhood of the pump allows to check and to calculate the N.P.S.H. value. A manometer installed near the exit orifice for the measurement of the operating pressure. -
Page 10: Operation
OPERATION START OF THE PUMP Before starting the pump you should take the following steps: a) please make sure that the delivery and the suction tubes are correctly connected and that all the bolts are well tightened. b) Full open the gate valve on the suction line and the one of the air vent line, but not before having fully closed the delivery valve and the vent valve located on the suction manifold. -
Page 11: Temperatures
TEMPERATURES For the correct operation of the machine should be observed the following temperature values, which are listed on the data sheet. Moreover we indicate the maximum and minimum operating temperatures, which have to be strictly observed for a continuous working cycle of eight hours. 0°... -
Page 12: Hints On Correct Operation
HINTS ON CORRECT OPERATION PREVENTIVE MAINTENANCE The functionality of the pump depends on the number of working hours, the service conditions, the used construction materials and on the care with which the pump is treated during its operative life. A daily check during operation helps to avoid complications and assures an immediate intervention in case of damages. -
Page 13: Eventual Dry Functioning Of The Pump
Recommended Safety Measures To operate in conditions of extreme safety during the control of the running machine the operator should be adequately equipped. Rubber boots, anti-acid overalls and helmet with protective visor for the face are the indispensable equipment for the persons who have to operate without running the risk of physical damages. The described operations have to be carried out by skilled staff. -
Page 14: Troubles And Eventual Causes
TROUBLES AND EVENTUAL CAUSES THE PUMP DOES NOT EROGATE ANY LIQUID The pump and the suction tube are not completely filled with liquid. There are air pockets, which have to be purged. The non-return valve on the suction tube is blocked and totally closed. The impeller is blocked by rubbish or incrostations present in the liquid. -
Page 15: The Pump Cause Vibration And Noise
THE PUMP CAUSES VIBRATION AND NOISE 24) Operation at a capacity, which is too low for the application. 25) The tubes or the foundations are not sufficiently rigid. 26) The motor bearings are worn out or damaged. See also points 6-22. 27) The pump is subject to cavitation. -

Page 20: Recommended Spare Parts
Useful indications The assembly and disassembly operations of the pump can be performed exclusively by persons who have got basic mechanical knowledge and skills. For a better understanding of the characteristic features sufficient notions on the materials, which are used for the construction of the machine, are indispensable. RECOMMENDED SPARE PARTS To determine the minimum quantity of spare parts, which should be available for eventual replacements, you should take into consideration the operating conditions (more or less heavy) and the number of...
