Diaphragm Pump

Diaphragm Pump – Controllable

Tiermax diaphragm pumps are positive displacement oscillating pumps used for liquid dosing. A diaphragm separates the medium to be conveyed from the drive. As a result, it is shielded from the medium’s harmful effects. They are used wherever precise and leak-free dosing is required, such as with corrosive, malodorous, abrasive, radioactive, flammable, viscous, or toxic media. Flow rate adjustment via external frequency converter stroke frequency adjustment and manual stroke length adjustment for optimal adjustment to any requirements.

Tiermax offers a variety of diaphragm pumps to suit your application and needs, including:

• Diaphragm pump

• Multi-layer diaphragm pump

• Solenoid diaphragm pump

• Piston diaphragm pump

Tiermax controllable diaphragm pumps are electronic dosing pumps that can be used in a variety of applications. They are intended for industrial use and provide maximum operational reliability.

Our diaphragm pumps are positive displacement oscillating pumps used for liquid dosing. A diaphragm separates the medium to be conveyed from the drive. As a result, it is shielded from the medium’s harmful effects. They are used wherever precise and leak-free dosing is required, such as with corrosive, malodorous, abrasive, radioactive, flammable, viscous, or toxic media. Flow rate adjustment via external frequency converter stroke frequency adjustment and manual stroke length adjustment for optimal adjustment to any requirements.

Special Designs

Individual solutions for special dosing tasks are available, such as pump bodies with special nominal widths, double valve designs and valves with spring loading, with elastic ball seats, flushing devices for interval or final flushing to prevent sediments in pump bodies, integration of stroke encoders, diaphragm rupture monitoring, and special materials such as titanium or Hastelloy with a cleanable design.

Multi-layer diaphragms can be used to complete complex dosing tasks while maintaining technical safety. The significantly longer diaphragm service life compared to single-layer diaphragms and diaphragm monitoring take into account the higher safety requirements (pressure switches, manometers, etc.).
