News for 2005

Read about the news prepared by us for the next year.

Dear customers and business partners,

We are in the second year of the collaboration of our companies in the area of special pumps which account for only 20 % of our production at the moment. This year we commenced the development and manufacture of so-called “hermetic” pumps with wading rotor. The main advantage offered by them to the users is the containment of the pumped liquid in closed system without any leakage even during a failure. They are designed for pumping liquids with adverse effect on the environment and human health and were asked from us by a Czech company being unsatisfied with the imported pumps and intenting to find a Czech manufacturer. They represent a highly specialized product in which various influences and physical laws are reflected and must be observed when designing them. On the first prototype we verified the properties, shape and construction as well as reliability of operation of the designed bearings. The trial operation of the prototype using the regular working fluid will be completed by the end of this year. The trial operation will be conducted together with the controlling with should provide the answers to our questions regarding reliability, service life, range of operational and technical parameters, applicability for liquids of various properties, motor power consumption variations depending on the pumped substance temperature and viscosity as well as appropriateness and quality of the used components. We will have the answers to these questions in a short time.

Simultaneously with this project our existing hermetic pumps with magnetic coupling called METABLOC-MAG are innovated. As indicated by the name, the pumps feature monobloc configuration the main advantage of which for the customers is the reduction of installation area and lower acquisition costs. Two types are designed: standard and special. The STANDARD type is the existing META-MAK pump in monoblock configuration including the traditional application – standard clean liquid plus flammable liquid of working temperature up to 260 °C. The SPECIAL type offers a special design allowing to pump liquids which are very hot any may contain both solid and magnetic admixtures. The benefit for the user rests in the fact the admixtures cannot cause the pump breakdown as in the case of the traditional pump since the pump is capable to manage any adverse admixtures in the pumped liquid. It can be applied for both the clean and contaminated liquids including magnetic admixtures, both the chemically active and neutral liquids and flammable liquids particularly in chemical, petrochemical and pharmaceutical industries, power engineering and water management. Main operating parameters: working temperature: -40 °C to +400 °C, working pressure: up to 25 bar, fluid density: 600 kg/m3 to 1500 kg/m3, kinematic viscosity: up to 75 mm2/s, solid admixtures: up to 2 mass %, grain size: up to 0.5 mm, motor power consumption: up to 55 kW. The pumps are expected to supplement or replace the existing hermetic pumps.

Finally, I want to note the progressive innovation process and development of new products is of great importance from the viewpoint of the company viability. Without adequate efforts in these areas no success at local or global markets can be expected in long-term perspective.
