This year, Termomeccanica Pompe has launched its new AP pump line, overhung solution, OH2 type, designed for heavy duty process in accordance with API standards 610, 10th edition (ISO 13709:2003).
Development of new API pump line
The development of this new pump family is part of TM.P.’s strategic expansion plan which includes amongst its key goals the strengthening of the company’s presence in the Petrochemical and Oil & Gas markets with the view to substantially increase sales and thus become recognized, in the mid-term, as a well-established international competitor of the sector.
The new AP pump family originates from the old AP series manufactured and commercialised from the 1960s onward, but now discontinued. It is made of 50 completely standardized pumps developed with modular design so as to minimise delivery lead-times and optimise production as well as storage costs. In fact, the whole series is covered with only 5 frames (support/ bearing/ shaft).Additionally, all pumps of the family are suitable for the S5-S6-S8-C6-A7-A8-D1-D2 classes of materials as per API 610 standards.
New hydraulics have been studied for the entire pump series so as to allow energy savings through higher efficiency rates and to guarantee wider operation ranges too.
Ten different prototype pumps were actually manufactured and tested in TM.P.’s own Test Center facilities so as to check their mechanical behaviour related to vibration and noise levels throughout the entire operation range. Further high temperature performance tests (350°C) were conducted on some of the prototype pumps. Such tests were performed with diathermic oil in a special closed circuit allowing to check stress on main critical components, to measure thermal flows propagation from pump casing to support, as well as to implement solutions enabling the reduction of the lubrication oil temperature. It will be possible to use such test bed in the future to carry out mechanical running tests upon customer request.
