Why This Product

Motor-Driven Diaphragm — Precise and Pulsation-Free

Motor-driven diaphragm mechanism delivers chemically accurate dosing without the pressure variation of solenoid-driven designs. Consistent dose volume at each stroke regardless of back-pressure changes in the dosing line.

Grundfos Smart Digital Interface

DDA/DDC series pumps feature the Grundfos Smart Digital interface — touchscreen control, communication protocols (Profibus, Modbus, GENIbus), and external signal input for analogue control from analyzers and SCADA systems.

Chemical Resistance — PVDF and Stainless Construction

Liquid end components in PVDF (polyvinylidene fluoride), stainless steel, and EPDM/Viton for compatibility across a broad range of chemicals — acids, alkalis, oxidizers, and solvents used in water treatment and process applications.

Auto-Degas Function

Automatic degassing function purges gas bubbles from the pump head before dosing — critical for hypochlorite and other gas-releasing chemicals where air pockets cause dosing inaccuracy and pump damage.

Wide Flow Range with One Pump

Variable stroke frequency and length provide a wide effective flow range from a single pump — one pump covers multiple dosing rate requirements without requiring different pump models.

Leak Detection and Dry-Run Protection

Integrated leak detection and dry-run protection prevent chemical spills and pump damage from empty chemical containers — important safety features for unattended dosing installations.

Important Notices
Electrical Requires correctly rated supply — 120-240V, 1-Phase, 60 Hz. Install with correctly rated circuit protection and motor starter.
Temperature limits Do not exceed max fluid temperature per nameplate. Operating outside these limits will damage seals and motor insulation.
Dry running Do not run dry. DME940-4AR pumps use the pumped fluid to lubricate the shaft seal — dry running destroys the seal within seconds. Install dry-run protection on all automatic installations.
Maintenance Refer to the Grundfos Installation and Operating Manual (IOM) for correct installation, commissioning, and maintenance intervals. Contact PumpStop for documentation.
