Solenoid - Diaphragm Dosing Pump

Solenoid – Diaphragm Dosing Pump

Diaphragm dosing pumps are leak-free, and are therefore suitable for highly aggressive or toxic media. Depending on the gear type, the diaphragm allows pressures up to 16 bar. Diaphragm dosing pumps are fitted with a separation chamber as standard. If a crack forms in the diaphragm due to wear, this prevents the medium from flooding the system components or the pump itself. The medium is controlled and flows through a downpipe to the collecting basin. The medium sides of the diaphragms are coated with PTFE

Motor Driven  Piston Dosing Pump

Piston dosing pumps are particularly precise dosing units, which are not dependent on pressure. Dosing capacity varies proportionally with the stroke length and can be set to the tiniest repeatable quantities. Two-piston and multiple-piston pumps are therefore particularly suitable for delivering precise mixtures, where different media must be mixed at a constant ratio which can be selected as desired. Using externally controlled drive motors, the total quantity can be varied from 5% to 100% at a constant ratio. Heated heads allow the dosing of media that are torpid when cold. A piston flushing skirt is available as an option, to prevent damaging leaks and protect the packing materials and pistons from abrasive chemicals.

The dosing quantity can be doubled by using two dosing heads. The largest motor-driven diaphragm dosing pump (Type GMR) has a hydraulically coupled double-diaphragm system.

Peristaltic

Peristaltic pumps are the simplest types of dosing pumps. With their rotary displacement body, they are very maintenance-friendly and allow optimal dosing at low back-pressures for simple applications. Various performance classes are available, with different delivery capacities, back-pressures and control specifications

The CR range offers pumps of unmatched reliability that can be intelligently tailored to suit an infinite variety of applications. Since Grundfos invented this type of multistage in-line pump in 1972, many imitations have appeared on the market. However, four decades on, this latest generation of CR pumps, with their traditional efficiency, reliable performance and adaptability, remain the wisest choice.

The basic CR pump range is available in four different materials: cast iron, two grades of corrosion-resistant stainless steel, and all-titanium.
