features RL-RJL-RFL

A pin-type joint, the true heart of the cavity pump, offering the best solution of its type currently available on the market. Superior durability, reliability and maintenance costs, it successfully combines an extremely compact size with incomparable robustness. Its special construction allows the axial loads and torques to be split into different elements, which makes it unique. In addition to this, replacing worn components is inexpensive, due to the added bushings in the areas of wear, which avoids having to replace costly components (rotors, drive shaft and hollow shaft).

The pump can be installed without a stand. This helps to reduce the overall dimensions and avoids additional costs. When necessary, stands, customised skids and trolleys can be provided, allowing the pump to be moved.

The parts of the RL Series pumps which are in contact with the product can be manufactured from different materials, from the cast iron version (GG25) to stainless steel (AISI Type 304 and AISI Type 316). However, the cast iron versions still have the rotating parts made from AISI Type 304 and AISI Type 316 stainless steel.

Very low pulsation and tensional stress.  The centrifugal effect is reduced to a minimum, due to its low operating speed and the predominantly axial pump system.

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.

Durability, reliability and low energy consumption. The RL series successfully combines a compact size with high performance in one single product.

The RL Series is designed to be versatile in all of its applications, which is why it can be arranged with options and accessories that are suitable for every application.  In addition to this, there are the benefits that the special characteristics of a cavity pump can naturally offer in pumping various kinds of fluids, fluids with low to very high viscosity, clean fluids or those containing solids of various types and sizes.

All the drives installed on the RL Series have been endurance-tested and have been subjected to strict and stringent technical testing.  We can install either electrical or hydraulic motors.

All models of electrical motor reducers and variators have certain features in terms of robustness, dimensions of the bearings and quality of the gears.

The highest possible standards, exceptional operating efficiency due to its excellent volumetric efficiency, even at high pressures, and minimal energy consumption.  All the hydraulics on the RL series have been calculated to ensure the best you can find anywhere on the market today.

Each component is manufactured to very stringent quality specifications. The finishing and the precision of each component are the starting point for every single pump built. All components are subject to specific controls according to their features and their functionality.

The RL Series is designed to ensure easy maintenance, with only a minimum number of replacement parts necessary.

In particular the bushings on the joint enable it be completely replaced without having to replace the shafts and rotors.  Maintenance costs are thus reduced.  The cost of the machine is also highly competitive, considering its entire life-cycle.

Due to the compact size of its components, the RL Series successfully combines incomparable technical features with very competitive costs. Its modular design enables the right solution to be offered for each specific application, which avoids having to pay for any unnecessary features. All of which increases competitivity.

The special features of the hydraulic parts of the wobble pump allow excellent priming abilities (up to 4m). The pumps in the RL Series are designed to create the lowest possible pressure drop in the pump housing, due to the wide sections, a compact joint and its fluid dynamic design.
