Design features
The separation of liquid chamber/atmosphere by means of an isolation shell is the best solution to pump aggressive, explosive and toxic liquids, hydrocarbons, heat transfer liquids and liquids difficult to seal.
The hermetic sealless design is indispensable for the chemical, pharmaceutical and petrochemical industries.
A wide range of pumps covers the different performances. Low flow and high heads are the main characteristics of this pump design.
The hydraulic part of the pump is equipped with a self-balancing impeller, which has a positive effect on the service life of the unit.
High quality casting of pump housing and impeller.
RWP QUICK CHANGE CARTRIDGE KIT to guarantee an easy and fast maintenance.
The rear shell is made of one single piece, no welding, ellipsoidal profile that has been studied to withstand higher pressures than the traditional one.
AISI 316 is the standard construction (with pressure up to 25 bar), Hastelloy® C276 and titanium alloy upgrade when higher pressure ratings and increased efficiency are required (with pressure up to 150 bar).
High power synchronous magnetic coupling is mechanically locked with rare earth magnetic elements. The high performance magnets can operate at liquid temperatures of up to 662°F (350 °C) without external cooling.
Field assembling of the product lubricated bearing arrangement does not require special tools.
The bearing materials are available in different materials to provide the best solution for each application: Silicon Carbide (SSIC), Tungsten Carbide (WC), Carbon to allow accidental dry running transitory and PTFEC/G or PEEK compound (for any applications where the Carbon cannot be used.) The use of elastic rings reduces the sleeve bearing loads and the thrust bearing loads to the minimum, to guarantee many years of maintenance-free operation.
