Pump construction
Close-coupled drivers are conventional drivers mounted directly to pumps frame. No base, coupling or guards
are required for this mounting style.

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 is the best solution for the chemical, pharmaceutical and petrochemical industry. A wide range of pumps covers the different performances. Low fl ow and high heads are the main characteristics of this pump design.
Field assembling of the product lubricated bearing arrangement does not require special tools. The bearing materials are available in four different types to provide the best solution for each application: Silicon Carbide (SSIC), Tungsten Carbide (TC) , Carbon to allow a dry running situation and PTFEC/G (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.
CF8M Pump Casing & Impeller high quality casting components.
Other materials:
– Hastelloy®C276,
– Incoloy®825,
– Duplex, or others available on request.
RWP QUICK CHANGE CARTRIDGE KIT
to guarantee an easy and fast maintenance.
Epoxy primer and poly-acrylic enamel water-based painting for the best quality resistance linked to the environmental respect.
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. Hastelloy®-C276 is our standard isolation shell material – providing a safe and efficient solution – system pressure max 150 bar. Titanium Alloy is an upgrade when higher pressure ratings and increased efficiency are required.
High power synchronous magnetic coupling designed by our Technical Office and with rare earth magnetic elements mechanically locked.
The high performance magnets can be operated at liquid temperatures of up to 662°F (350°C) without external cooling.
The sealing system with flat gaskets prevents from leaking in the atmosphere.
Different materials available:
– Asbestos free
– PTFE
– Graphoil
– Gylon®
