- Magnetically driven, sealless design eliminates dynamic leak paths; a static sealed containment shell replaces traditional shaft seals, removing a common source of chemical leaks and environmental exposure
- Rotary gear technology provides pulseless, laminar flow — no dampeners required and no flow drift over time, unlike peristaltic tube-based pumps
- Integrated variable frequency drive, brushless DC motor, and controller in one IP66 / NEMA 4X enclosure eliminates separate VFDs, wiring, control panels, baseplates, and dampening accessories
- Predictive maintenance via onboard diagnostics: continuously monitors flow, speed, and current; generates maintenance alerts based on actual pump wear rather than elapsed time or cycle counts, enabling planned service and avoiding unexpected downtime
- Front pull-out (Rapid Repair-in-Place) design allows complete gear and liner replacement in minutes without disconnecting piping or disturbing system alignment; reducing service downtime significantly compared to other pump technologies manufacturer states this can cut service downtime by as much as half compared to conventional designs
- Handles off-gassing chemicals such as sodium hypochlorite without loss of prime and without special degassing valves or recirculating devices
- Self-priming to 5 ft depth with a foot valve; automatic dry-run shutdown within 10 seconds of detecting low or no flow
- 7-inch color touchscreen with guided commissioning ("Enter and Go" interface); setup parameters can be cloned from one unit to another, reducing programming time across multi-pump installations
- Firmware and interface are field-updatable via USB, allowing ongoing performance improvements and new control modes to be deployed to installed units
- Available mounting bracket supports wall mounting in vertical or horizontal orientations; touchscreen display rotates to match preferred orientation
- Flow meter option (standard PVDF paddle type) provides +/- 1.0% full-scale accuracy and enables closed-loop flow control, failure mode detection, and real-time predictive maintenance based on actual flow data
- SCADA integration via 4-20mA, Modbus, and 4 programmable relay outputs (dry contacts); Ethernet IP planned for Q1 '27
- BABAA compliant; NSF/ANSI/CAN 61 and 372 certification for drinking water in process
- Three-year warranty on non-wearing parts; manufacturer states up to 400% longer service intervals versus traditional rotary gear pumps, with typical gear and liner replacement intervals of 18–24 months
Pulsafeeder Eclipse Pro
The Pulsafeeder Eclipse Pro is a positive displacement, magnetically driven rotary gear metering pump designed for precise, pulseless chemical dosing in industrial and municipal water and wastewater treatment applications. Built on the proven Eclipse E02 mag-drive gear pump platform, it integrates the pump, brushless DC motor, variable frequency drive, and controller into a single compact unit — eliminating the need for external VFDs, control panels, dampeners, and calibration columns. The pump maintains constant flow regardless of pressure fluctuations through integrated digital monitoring, and its onboard self-diagnostics deliver predictive maintenance alerts before service is needed rather than relying on timers or cycle counters.
The Pulsafeeder Eclipse Pro is BABAA (Build America, Buy America Act) Compliant.
