- Page 3 1. Introduction 1.1 General This manual refers to ADH horizontal centrifugal pumps series. Pumps of series ADH are made of thermoplastic materials (Polypropylene or PVDF) and can be of different sizes. Dimensions and capacities available are described in paragraph 7. 1.2 Purpose of the manual The main purpose of this manual is to assure that the activities of installation, operation and maintenance of the pumps are executed in a correct and safe way by all personnel in charge of these operations.
- Page 4 1.5 Explosive Atmosphere Zones The pumps described in this manual CANNOT be used in explosive atmospheres. These uses require special pumps that AlphaDynamic Pumps SA manufactures with particular materials and precautions. Customers who want to use special pumps in these kind of zones have to contact the AlphaDynamic Pumps SA technical office for the correct choice of the product.
- Page 5 These pumps have been designed and manufactured to be used in specific conditions and within defined limits. The use outside these specifications has to be agreed and approved by the AlphaDynamic Pumps SA technical service. It must also be considered that, if the pumps are used outside their technical specifications, the CE Certifications and the warranty are no longer valid.
- Page 6 2.2 Receipt and Inspection Even if AlphaDynamic Pumps SA takes all the necessary precautions during packaging, we suggest that you carefully check the received material. Check for any missing parts caused by the courier and/or by AlphaDynamic Pumps SA Check the data on the label of the received pump and compare it with those relative to your purchase order.
- Page 7 2.2.3 Working principles ADH horizontal, centrifugal pumps must be installed below head with appropriate procedures to avoid vortex formation and consequent air bubble suction. The pump must work ONLY when PRIMED. The impeller - integrally joined to the shaft and to the direct drive mounted motor- must be set in rotation at a preset speed (max 2.900 revs/min).

- Page 11 2.5 Hydraulic system The pump is generally part of a hydraulic system that can include a various number of components such as: valves, fittings, filters, expansion joints, instruments, etc. The way the piping is arranged and the position of the components has a great influence on the operation and on the life of the pump. 2.6 Pipes Connection Position the pump as near as possible to the liquid source and under the level of the liquid (under head).
- Page 12 If the temperature of the pumped liquid represents a critical factor, install in the system a thermometer, preferably on the suction line. These control instruments can advise of abnormal operating conditions of pumps such as: accidentally closed valves, missing liquid, overloads etc. 2.8 Motor connection Check that the voltage and frequency printed on the label of the motor correspond to those of the electric system to be used.
- Page 13 do not run the pump dry (Note: the design of ADH horizontal centrifugal pumps don't allow dry- running because it causes damage to the inner components of the pump). start the motor for only one or two seconds to check that the direction of rotation is the same as the arrow on the pump head.
- Page 14 DO NOT ALLOW THE PUMP TO RUN DRY (note: the ADH horizontal centrifugal pump design doesn't allow dry-running operation because it will damage irrevocably the inner parts of the pump) An accidental failure can generate sparks up to considerable distances. In case of vibrations or abnormal noises, stop the pump immediately.
- Page 15 3.5 Starting Start the electric motor and gradually open the discharge pipe until you reach the required flow. The pump can't operate more than two or three minutes with its discharge closed. A longer period can cause serious damage to the pump. If the pressure shown on the pressure gauge on the discharge piping does not increase, stop the pump immediately and release the pressure carefully.
- Page 16 AlphaDynamic Pumps SA to find an alternative solution. If the pump is temporarily removed from the system and kept in stock, it's necessary to follow the instructions of paragraph 2.3 "Storage". 3.9 Noise Level In some circumstances, for example when the pump works with high pressure and low capacity, the increase of the noise can be disturbing for the personnel working in the proximity.
- Page 17 4.2 Inspections In general, ADH horizontal centrifugal pumps do not need a "routine" maintenance and most of all they don't require frequent dismantling. However, periodical inspection is advisable to verify the state of wear of the impeller, the shaft and the bearings and if the general conditions of the internal parts of the pump are good. The time between the inspections is strongly dependent on the operating conditions of the pump: the characteristics of the liquid, the temperature, the materials used and obviously the time of operation.
- Page 18 4.4 Start-up The installer/operator must always use material compatible with the pumped liquid and in line with the pump design. WARNING: it is forbidden to use liquids that are incompatible with the construction materials of the pump’s components or in an environment where there are incompatible liquids. In order to start-up the pump, proceed as follows: 1 Check that the suction and delivery pipes are correctly connected.
- Page 19 B. check the tightening of all bolts. C. check the product pipes. The noise level of the machine corresponds to: The sound pressure level of the A weighted emission, in the working place, is less than 75 dB. 4.5 Standard maintenance time schedule In order to guarantee performance and safe use, ADH pumps need standard maintenance operations throughout their life span and in accordance to the time-schedule detailed in the following table.
- Page 20 aprons, etc.). LIQUID EJECTION HAZARD. WARNING: To clean the pump, only use a clean cloth, moistened with an appropriate detergent: 1. Disconnect the liquid suction and discharge pipes of the pump 2. Disconnect the electrical power supply cable from the motor 3.
- Page 21 PRODUCT LEAKAGE HAZARD. WARNING: check that there is no sediment inside the pump, if so, remove. A5 Proceed with reassembly, following the inverse order and fasten the bolts on the pump cover evenly. The impeller cleaning and/or replacement is now completed and it is now possible to reposition and connect the pump as described in the previous Chapters.
- Page 22 4.8.1 Sealing and motor assembly In order to assemble the sealing and the motor, proceed as follows: C1 If the motor is being assembled for the first time, fit the pump shaft into its housing and gradually screw the lock nuts tight. NOTE: Tighten the nuts in a progressive sequence, to ensure perfect tolerances.
- Page 23 WARNING: all Oring and gaskets must be replaced every time the pump is opened. PRODUCT LEAKAGE HAZARD. C9 Fit the O-ring seal and the impeller on the shaft. C10 Fit the front O-ring seal and the nut and tighten until the impeller is locked. C11 Reassemble the pump casing and the fastening screws and evenly tighten with a cross sequence.
