Dosing Pump for Liquid Transfer SSP Series N

SSP Series N stainless steel rotary lobe dosing pumps have been specifically designed for low volume fluid transfer such as dosing within applications like laboratories, pilot plants, chemical processing, food processing, electroplating, and film processing.

Series N pumps feature a compact design, making them ideal for installation where space is at a premium. Whilst small in size, Series N rotary lobe pumps still provide the same high quality low shear pumping for maximum performance and reliability.

Compact Size

Series N dosing pumps feature a small, compact design, ideal for installations where space is restricted.

Bi-Directional Pumping

The Series N pump is fitted with roloid gear rotors keyed to the shafts and held by retention discs enabling bi-directional pumping.

Durable Design

Rotors are manufactured from 316 type stainless steel which is PTFE impregnated for low friction flow. The rotors are suitable for operation at temperatures up to 100˚C.

Cast Iron Gearbox

The Series N pump has a robust cast iron gearbox which provides maximum shaft rigidity.

Reliable Low Volume Fluid Transfer

Series N liquid transfer pumps are designed specifically to handle low fluid transfer duties such as dosing in a range of industries and applications.

Space Saving Design

The small size and compact design of these pumps mean they are highly suited to applications where space is limited.

Easy Maintenance

Simplified construction is designed to make maintenance easy and hassle free, saving time and money.

Zero Product Contamination

The non-contacting roloid gear rotors ensure product contamination is eliminated, protecting your sensitive liquid products.

Multiple Seal Options

Either single mechanical seals or packed glands may be fitted to the pump. Mechanical seals are available in durable materials such as silicon carbide to help you meet the demands of your application. Alternatively, packed glands offer a simple, low cost, and easy to maintain controlled leakage sealing solution.
