Double Diaphragm Pumps
1:1

Minimum pulsation
Minimal changeover times in conjunction with the short-stroke principle of the pumps reduce pulsation to a minimum and ensure a more uniform media flow.

Maximisation of service life
The ceramic slide valve that is used works virtually free of wear. The short-stroke principle prevents over-extension of the diaphragm and thus enables a long service life.

Increased process reliability
Safe start-up of the pump is ensured, even in critical operating situations. The bistable, over-centre valve prevents problematic intermediate positions of the control valve.

Reduced compressed air costs
Optimised geometries with minimal dead spaces, as well as the extremely low start-up pressures, starting at 0.7 bar, reduce energy consumption to a minimum.

Easy conversion in existing systems
Small, compact design thanks to optimised valve technology

Minimal maintenance costs
The durable short-stroke diaphragms, the low-wear ceramic slide valve and the maintenance-friendly structure of the pump guarantee extremely low service costs.

ATEX
Timmer pumps are in accordance with the ATEX directive.
