Metering pumps are divided into reciprocating and diaphragm pumps, with several variations. Main characteristics of piston carriers:
1. Suitable for fluids without fluorogenic particles.
2. No absolute tightness system is required.
3. High pressure is required.
4. High delivery accuracy.
Accordingly, the diaphragmatic ones
1. Suitable for fluids with a small amount of suspended particles.
2. Toxic solutions where a completely sealed system is necessary.
3. No requirement for high pressure.
SR series
Dosing pumps with spring return mechanism, use a reduction box (with grease or in an oil bath) and standard four-pole electric motors with B14 bearing. Available in a number of versions, with various construction materials and types of control, pneumatic operation and ATEX explosion-proof type.
A (Plunger) plungers
Particularly popular economic series with very high precision due to the operating principle, performance range 0.8-1.458lt/h. Also available pneumatic type.
FM – D (Mechanical Diaphragm) Mechanical diaphragm
The FM is the most economical solution of the entire SR range, available for delivery up to 47lt/h. Accordingly, D is suitable for heavy-duty applications and a higher flow of up to 574lt/h.
B-BR (Hydraulic Diaphragm)
Due to the hydraulic principle of operation, they develop higher pressures than D/FM in a wider range of 1.5-1.068lt/h. The BR series is equipped with an overpressure relief diaphragm protection valve.
SD (Sandwich Hydraulic Diaphragm) Double hydraulic diaphragm
Top version of SR that provides maximum safety (due to double membrane in a range of benefits and high pressures similar to B-BR, they include an overpressure valve while their main advantage compared to BR is a membrane rupture detection system.
PDP series
Positive displacement metering pumps manufactured to API 675. Capable of manual operation (0-100%), electronic automatic control (4-20mA, 0-10V) and pneumatic.
A-I (Plunger) plungers
Simple and reliable design for easy maintenance.
SDI (Sandwich Hydraulic Diaphragm) Double hydraulic diaphragm
They are the best proposal for applications and processes that require high security and precision. Equipped with an overpressure protection valve and membrane rupture detection system.
