Description
The Grundfos 96529123 (DME375-10B PP/E/G-F-31A4A4B) is a Digital dosing pumps 120-240V 1-Phase — Digital diaphragm dosing pumps with internal brushless motor drive. Designed for Process liquids transfer, Cooling, Industrial process water treatment.
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.

| 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. DME375-10B 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. |
