Wobble R series
floating stator for Industrial, environmental and food sector
Our range of wobble pumps is the ideal solution for those seeking a highly compact and versatile product. They are particularly easy and economical to maintain, due to the very small number of component parts. They can be used in a variety of industrial applications due to their ability to pump products which are viscous, which have solids in the fluid or which are mildly abrasive. Perfect for those seeking a highly efficient, economical product, these offer an unparalleled cost/benefit advantage. Even at high rpms, they pump without pulsating and there is virtually no centrifugal effect. They are also suitable for use within the food industry, as there are no dead zones within the pump.
The R series range of pumps all have solidly constructed housings in cast iron, bronze and stainless steel (AISI Type 304 and AISI Type 316), manufactured using lost wax casting technology.
Food use: Stainless steel pumps can be supplied with FDA components or according to UNI EN 1935:2004.
Threaded GAS BSP connections are available as standard, but we can also supply DIN 11851 type adaptors upon request.

Materials
Casing materials
Wide selection of cast iron, and stainless steel bodies, including corrosion-resistant options for harsh environments.
Seal Shaft Materials
The R Series is designed to ensure easy maintenance, with only a minimum number of replacement parts necessary. In particular the cross-joint is easy to replace due to its reduced dimensions, enabling it to be completely replaced without having to replace shafts and rotors. Maintenance costs are thus reduced. The cost of the machine is also highly competitive, considering its entire life-cycle.
Materials of Rotors
Steel and special alloy materials long-lasting durability and resistance.
Materials of Stators
We offer a wide selection of compound materials for stators, designed to ensure high performance and durability in diverse industrial environments.
Among the available options, we can provide elastomers and special materials, including food-grade compounds and high-performance solutions.
Connections
Cross-type joints, the true heart of the wobble pump, offer the best solution currently available on the market. Cast-manufactured, highly durable and reliable, due to the high degree of engineering being achieved. Its special construction allows the axial loads and torques on the two axes of rotation to be split, ensuring only rotary movements of the pins that compose it. Its smaller dimensions mean that it can be replaced quickly.
Sealing Systems
The pump uses internal single mechanical seals as standard. The seal is located inside the pump housing. This solution ensures the maximum heat exchange between the surface of the seal and the product being pumped, which gives the benefit of increased durability. Moreover, the position of the seal makes it much easier to keep clean, thus avoiding product residues that could negatively affect operating conditions. The housings are suitable for the installation of seals manufactured in accordance with ISO EN 12756.
