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 — 100-240V, 1-Phase, 50, 60 Hz. Install with correctly rated circuit protection and motor starter.
Temperature limits	Do not exceed max fluid temperature 122°F or max ambient temperature 113°F. Operating outside these limits will damage seals and motor insulation.
Dry running	Do not run dry. DDE 200-4 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.
