SR Series Diaphragm Dosing Pumps, Type B and BR

Description

Hydraulic spring-return diaphragm dosing pump

Hydraulic diaphragm dosing pumps series “B & BR” are typically used when:

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

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 at standstill and during operation, manually or automatically via an actuator controlled by a 4–20 mA signal; bus interface; or pneumatically. The BR version features a built-in relief valve in the hydraulic housing to protect the diaphragm from overpressure.

Additionally, these pumps comply with ATEX standards and can be installed in hazardous areas.

A wide selection of wetted materials is available: SS 316L; PVC; PP; PVDF; PTFE; other materials on request.
