Horizontal Sealless Motor Pump
Fives' Cryomec HSMP pump (Horizontal Sealless Motor Pump) is dedicated to small scale transfer applications.
The main advantage of this encapsulated design is the absence of seal system between the cryogenic and motor parts. The bearings are life time bearings for smooth operation, avoiding technicians’ intervention for manual regreasing
This sealless pump is mainly used in ATEX areas (explosive atmospheres), for hydrocarbon liquids like LNG or methane, high suction pressure gases like carbon dioxide and expensive liquids like pure argon.
With its high-end design, Fives' Cryomec HSMP pump - equipped with a motor - is totally encapsulated (IP6x), implying that the equipment is entirely safe when pumping hydrocarbon or dangerous liquids, such as CO.
Fives' Cryomec HSMP pumps are designed to be able to take over 4’000 hours of duty – 4 times higher compared with mechanical seal pumps - a key asset for the equipment's reliability and your fluid transfer’s reliability.
Due to its high-end mechanical design, the maintenance is reduced to the strict minimum as there is no seal.
Moreover, there is no seal gas requested by this pump and the number of wear parts is reduced which optimize the total cost of ownership (TCO).
