New SPX Flow pumps for transfer of hot oil and water
Pumping solutions manufacturer SPX Flow has introduced the air-cooled CombiTherm Plus pumps to provide safe, efficient transfer of hot oil or hot water in a wide range of applications.
The pumps keep fluid temperatures uniform to ensure processes are efficient and predictable while their design protects seal faces and bearings from the heat of the fluid, providing durable, low maintenance, long life operation.
The design of the CombiTherm Plus pumps provides enhanced cooling using optimised fans and large fins to keep the temperature around the shaft sealing below 104°C even at high process temperatures of up to 350°C.
The heavy duty centrifugal pumps are centreline-mounted, which allows thermal expansion without affecting shaft alignment.
The combination of low temperature and perfect alignment protects seals and bearings, meaning that the unit provides long service life while minimising maintenance overheads.
The pumps are designed to handle high pressure throughout their flow range with hot oil pumps operating up to 360psi and hot water pumps up to 450psi.
Both CombiTherm Plus hot oil and hot water pumps use a balanced single mechanical seal that is easy to position and assemble for straight forward maintenance.
To prevent the grease from being washed out of the ball bearings, in case of a mechanical seal failure, the bearings are protected with two separate seals and an open drain.
The out-board seal of the quench chamber is running on a hardened shaft sleeve and the ball bearing area is sealed using contact-less seals to prevent wear on the shaft.
The hot oil pump has an open quench system with visual level indication and optional remote leakage detection, while the hot water model comes with a steam eliminator on the seal chamber.
Available for flows up to 1,330gpm, the modular CombiTherm Plus range comprises nine sizes in both hot water and hot oil model configurations to match many different application needs.
Units are sized so that they can be easily interchanged with other high-end pump versions so operators can easily upgrade their existing pumps.
