Grundfos Pumps Frequently Asked Questions

FAQ

What are Grundfos electronic dosing pumps?

Grundfos electronic dosing pumps are precision chemical dosing pumps designed to accurately inject controlled quantities of chemicals into water treatment, industrial and process systems.

What are Grundfos electronic dosing pumps commonly used for?

They are commonly used for water treatment, disinfection, pH correction, chemical conditioning, fertigation, cooling water treatment and industrial process dosing.

What is Grundfos SMART Digital dosing technology?

SMART Digital technology uses electronically controlled drive systems to provide precise, consistent chemical dosing across a wide operating range.

What is the difference between Grundfos SMART Digital S and SMART Digital XL pumps?

SMART Digital S pumps are designed primarily for lower-flow dosing applications, while SMART Digital XL pumps provide higher dosing capacities for larger water treatment and industrial systems.

What is the difference between Grundfos DDA, DDC and DDE dosing pumps?

DDA models provide the most advanced control and monitoring capabilities, DDC models offer flexible control for general dosing applications, and DDE models provide a simpler solution for straightforward chemical dosing.

What does FCM mean on a Grundfos DDA dosing pump?

FCM refers to the advanced FlowControl configuration, providing additional flow monitoring and diagnostic functionality for applications requiring greater dosing control.

What does AR mean on a Grundfos dosing pump?

AR identifies a control variant offering advanced external control options, allowing the dosing pump to integrate with wider process and automation systems.

What dosing modes are available on Grundfos electronic dosing pumps?

Depending on the model, available modes can include manual dosing, pulse control, analogue control, batch dosing and timer-based dosing.

Can Grundfos electronic dosing pumps provide proportional dosing?

Yes. Compatible models can adjust chemical dosing according to external pulse or analogue signals, making them suitable for proportional dosing applications.

Are Grundfos electronic dosing pumps suitable for water treatment?

Yes. They are widely suited to water and wastewater treatment applications requiring accurate and repeatable chemical injection.

Can Grundfos dosing pumps handle corrosive chemicals?

Yes, when the correct dosing head, valve, seal and wetted-material configuration is selected for the chemical being dosed.

What chemicals can Grundfos electronic dosing pumps handle?

Depending on the selected materials, they can be used with many treatment chemicals including acids, alkalis, disinfectants, coagulants and other liquid chemical additives.

How do I choose the correct Grundfos electronic dosing pump?

Consider the required flow rate, operating pressure, chemical compatibility, required control method, suction conditions and connection requirements.

What is the advantage of a wide dosing ratio?

A wide dosing ratio allows one pump to accurately cover a broad range of dosing rates, reducing the need to change pumps when process demand varies.

Are Grundfos electronic dosing pumps suitable for continuous operation?

Yes. When correctly sized, installed and maintained, they are designed for reliable dosing in continuous process applications.

Can Grundfos electronic dosing pumps be controlled remotely?

Depending on the model and configuration, pumps can accept external control signals and integrate with process control or automation systems.

What connection sizes are available for Grundfos electronic dosing pumps?

Connection sizes vary according to pump model and capacity, with different hose and pipe connection options available across the SMART Digital S, SMART Digital XL and DME ranges.

What is FlowControl on Grundfos dosing pumps?

FlowControl is an intelligent monitoring function available on selected DDA models that helps detect dosing irregularities and provides greater visibility of pump performance.
