Grundfos SMART Dosing

As experts in dosing, Duff Co. offers Grundfos’ advanced digital dosing pumps, in addition to a wide range of mechanical dosing solutions for pre-treatment and disinfection purposes. Grundfos’ SMART Digital Dosing pumps are specifically designed to safely and precisely dose even very small amounts of chemicals – all the way down to 0.0025 l/h (0.0000011 gpm). This makes for cost-effective operation, as you do not waste chemicals on overdosing. In addition, the risk of destroying your product by adding too much chemical is efficiently eliminated. And because the dosing is continuous, thus eliminating the frequent, stressful starts and stops as well as potential corrosion, the pump promises longer life.

With GruSMART Digitalndfos’ gentle yet powerful stepper motor, the stressful starts and stops are eliminated.

The dosing pump range also offers mechanical dosing pumps, which are capable of dosing up to 8,000 l/h (35 gpm) and of handling up to 200 bars (2900 psi) in special applications.

Duff stocks and distributes Stenner, Pulsafeeder, Chemtech,  Seko and other brands of chemical dosing and metering pumps.  Call or email our Parts Guru to find out the right pump for your application.

Stay tuned in early 2017 for new Grundfos dosing pump models! Warning: their signature green will be replaced with a deep red color that matches the Grundfos circulator pumps.
