  • Page 3 Sustainable Innovation, Quality Standardization and Dynamism Ekin has entered Turkey’s sector of the imported plate heat exchanger, with their customerfocused vision and dynamic. Ekin has expanded into new and upcoming investments. One of the main steps was gaining the identity of being a producer. Ekin has started the production of plate heat exchangers with the brand of “MIT”.

  • Page 6: Introduction

    1. INTRODUCTION 1.1 General This manual refers to mag drive centrifugal pumps of HTM series. Pumps of series HTM are made of thermoplastic materials (Polypropylene or PVDF) and can be of different sizes. 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 the personnel in charge of these operations.

  • Page 7: Installation

    1.5 Explosive Atmosphere Zones HTM PP/PVDF pumps CANNOT be used in explosive atmospheres. These uses require special pumps that GemmeCotti manufactures with particular materials and precautions. Customers who want to use special pumps in these kind of zones have to contact the Ekin Endüstriyel technical office for the correct choice of the product.
  • Page 8 The pump contains particularly powerful magnets. It’s forbidden for those who have cardiac pacemakers, defibrillators, electronic medical devices, metallic heart valves, metallic prosthesis or sickle cell anaemia, to handle or be in the proximity of the magnets contained inside the pumps. Consult a health care provider for specific recommendations before working with these pumps.
  • Page 9 The use of an electric starter is recommended. A simple switch can be insufficient to start and stop the electric motor connected to the main electric system. An appropriate starter: • Can prevent accidental starting after a failed attempt to start. •...
  • Page 10 2.4 Installation Ekin Endüstriyel is not responsible for injury to people or damage to things caused by the wrong installation of the pump or installation executed by non-qualified personnel. Install the pump in a position that guarantees a simple use. The unit v/pump has to be fixed on a rigid structure that will enable the support of the entire structure.
  • Page 11 The installation of a proper pressure gauge on both the suction and discharge piping is recommended. The installation of gauges allows an easy control of the correct functioning of the pump in relation with the required working point. In case of cavitation or other dysfunctions, the gauges will show evident pressure fluctuations.
  • Page 12 To avoid overloads on the pumps due to impurities or solid particles in the pumped liquid, the use of a filter in the suction line is strongly recommended. This filter has to be regularly checked to avoid obstruction. If unacceptable working conditions are revealed, the pump has to be automatically stopped and checked.

  • Page 13: Operation

    Read the following instructions to change the sense of rotation: • Wear individual homologated protection devices (e.g. gloves, glasses). • Make sure that the operating conditions are analogous to the specifications of the pump (see paragraph 7). • Install the pump in the hydraulic system. •...
  • Page 14 Do not reduce the suction. Reduction of the suction is responsible of the cavitation of the pump, which causes a loss of efficiency and a rapid wear. Reduction of the discharge are not advisable, if required, reduction of the capacity can be obtained by means of a valve installed on the discharge pipe.
  • Page 15 3.3 Temperature Increasing the temperature of the pumped liquid can damage the pump and/or the piping/fittings and there can be a situation of serious danger for the people in the nearby. Avoid sudden changes of the temperature and do not exceed the temperature specified in your order.
  • Page 16 The capacity and the head of the pump refer to water pumping at room temperature. If it pumps high temperature liquids or other viscosities and densities, the performances have to be proportionately decreased. Pumps of series HTM work well with liquids having a viscosity up to 100 CPS3 and specific gravity up to 1.9 .

    4. MAINTENANCE 4.1 General Dispositions During the warranty period extraordinary maintenance is allowed only for GemmeCotti personnel or personnel authorized by GemmeCotti. All the operations described in the paragraphs below have to be done exclusively by qualified staff and following step by step all the warnings written in this manual.
  • Page 18 The time between the inspections is strongly dependent on the operation conditions of the pump: the characteristics of the liquid, the temperature, the materials used and obviously the period of operation. After the first start-up of the pump we strongly recommend an inspection of the bearings after 3 months of functioning.

  • Page 20 4.4.2 Disassembling The Pump From The Motor 1. Remove the screws securing the pump and the motor flange (Photo N. 2) 2. Separate the pump from the motor (Photo N. 3) 3. If it’s necessary to remove the external magnet (Photo N. 4 in blue) from the motor shaft proceed unscrewing the grub screw with an Allen key and then use a puller to avoid damage to the motor shaft or the external magnet.
  • Page 21 5. Remove the group of the internal rotor (internal magnet, impeller with the front bearing - Photo No. 7) and check the wear of the shaft and the bearings (Photo No. 8). Pay attention that the shaft and the bearings are in ceramic and so very fragile. Then remove the rear casing and replace the external o-ring (Photo No.
  • Page 22 Always verify the correct placement of the bearings and then use a hand press for their complete introduction in seat. Make sure that when closing the pump, the o-ring is perfectly in seat and is not pinched. During the introduction of the pump on the motor pay attention to the magnetic attraction that can cause injury to fingers or hands.

    5. PROBLEM SOLUTIONS 6. SPARE PARTS 6.1 How To Order Spare Parts A complete kit of spare parts for these kinds of pumps is available. Please contact GemmeCotti or our distributors. To have the spare parts it’s necessary to communicate the model of the pump, the size, the material, the serial number, the year of construction and the number relative to the spare part required.

    7. DATA 7.1 Technical Data and Limits The performance curves are valid for homogeneous liquids with specific gravity = 1,viscosity 1 cPs and temperature of 20 °C. If the liquid to be pumped has a specific gravity higher than 1, the absorbed power written on the performance curve has to be increased according to the value of the specific gravity of the liquid.
