SR Series Diaphragm Dosing Pumps, Type D

Description

Spring-return diaphragm dosing pump

Mechanical diaphragm dosing pumps series ”D” are typically used when:

• The dosed fluid contains a small amount of suspended solids
• A sealed design is required
• The dosed fluid is toxic

Each pump is equipped with a standard gearbox system featuring a vertically mounted motor. The gearbox includes a contact-free worm and worm wheel mounted on a bearing fully immersed in an oil bath.

Stroke adjustment can be performed both at standstill and during operation, manually or automatically via an actuator controlled by a 4–20 mA signal; bus interface; or pneumatically. Like mechanical diaphragm pumps, they are easy to maintain. In addition, they comply with ATEX standards and can be installed in hazardous areas.

A wide selection of wetted materials is available: SS316L; PVC; PP; PVDF; PTFE; other materials available upon request.
