MONO Pumps has introduced the Series S range of stainless steel rotary lobe pumps. The pumps have a specification choice to optimise matching to the customer's application, backed by a number of features.

These include cleaning in place (CIP), ability to handle low to high viscosity pumped media, high efficiency, and the availability of pumps delivering high flow rates and pumping pressures.

The smooth, low shear pumping action is suitable for products such as creams, gels, emulsions, aerated mixtures, and delicate cells and organic solids in suspension.

This combined with modular design giving increasing levels of flexibility and easy cost-effective maintenance provides the customer with a high-quality pump solution for a diverse range of applications.

The Series S range is capable of flow rates up to 106m3/h and available with a wide range of displacements from 0.053 to 3.53 litres/rev and differential pressures up to 20 bar. Its cast iron gearbox provides maximum shaft rigidity and easy oil seal replacement.

The Series S1 to Series S4 pumps all use a universal gearbox design. This gives the flexibility of mounting pumps with the inlet and outlet ports in either a vertical or horizontal plane, simply by changing the foot and its position.

The Series S5 and S6 pumps have dedicated gearbox castings, which also allow the inlet and outlet ports to be in either the vertical or horizontal plane. A tough epoxy paint gearbox finish provides optimum protection against natural and corrosive elements.

The pumps with standard port connections have full through bore inlet and outlet ports, this reduces inlet and outlet port losses, thereby lowering NPSH requirements. Enlarged diameter and rectangular ports are available to handle very high viscosity pumped media.

In standard specification the pumps are supplied with tri-lobe rotors, a bi-lobe rotor option allows the handling of fluids containing large solids.

All rotors are available in three temperature ratings enabling the pump to be operated at maximum temperatures of 70, 130 and 200°C for both process and CIP.
