Solenoid Drive Pumps

Concept metering pumps are for basic water treatment applications.

Beta® Solenoid-Driven Diaphragm Metering Pump : 0.74 - 32 lph, 16 - 2 bar

Gamma X Solenoid-Driven Metering Pump : 2.3 – 45 lph, 25 – 2 bar

Delta Solenoid-Driven Diaphragm Metering Pump : 7.5 - 75 lph, 16 - 2 bar

Pneumatically-driven diaphragm metering pumps available.

Motor Drive Pumps

Sigma 1 : 17 - 120 lph                Sigma 2 : 50 - 350 lph                Sigma 3 : 145 - 1,030 lph

Robust motor-driven diaphragm metering pumps Excellent process safety and reliability is guaranteed with the patented multi-layer safety diaphragm. A variety of power end and control configurations. ATEX option.

Proven precision: microprocessor control with optimum combination of speed control and digital stroking frequency.

Metering is controlled via the easy-to-use operating menu and functions can be monitored at a glance via the back-lit LCD display.

Standard PVDF liquid ends with integrated safety bypass valve – always the right choice in practical applications. Stainless steel liquid ends are also available for special applications.

Maximum safety: the dual DEVELOPAN® diaphragm with sensor in the inter-diaphragm cavity guarantees effective

Protection even in the event of a diaphragm rupture.

                                                         Hydro   3 - 1,450 lph, 100 - 7 bar

The Hydro 2, 3, 4  hydraulic diaphragm pumps represent an integrated product range with stroke lengths of 15 and/or 20 mm. A wide range of power end versions is available for use in areas at risk from explosion with ATEX certification. The Hydro product range is designed to comply with API 675 among others.

Makro 5   38 - 6,108 lph, 320 – 4 bar

Excellent feed rates in the low pressure range. The Makro 5 is an integrated product range with stroke lengths of 20 and/or 50 mm. A wide range of power end versions is available for use in areas at risk from explosion with ATEX certification. API 675 option.


The Zentriplex® oscillating multi-cylinder process diaphragm pump excels through its high performance and high efficiency in combination with a minimal footprint. This extremely compact and lightweight new design allows high

Pressures and metering outputs to be achieved with minimal material costs and low drive power requirements.

Orlita Evolution Pumps   3 - 7,400 lph, 400 - 10 bar

Discover a new dimension in process reliability and flexibility: The new Orlita® Evolution from ProMinent is an extremely rugged range of hydraulic diaphragm process metering  pumps with hydraulically deflected safety diaphragm. Its modular design allows many combination options for implementation of multi-pump systems in the most diverse of applications.

Ultimate process reliability thanks to multi-layer PTFE diaphragm with integrated diaphragm rupture warning/indicator.

Integrated hydraulic overflow valve.

Reliable function thanks to continuous oil chamber venting.

Maximum flexibility thanks to modular design.
