MPD Series Integrated Pump Inverter - IE5 Efficiency & IES2 Rating, Smart Water Supply Solution

MPD Series Integrated Pump Inverter

The MPD Series is an integrated backpack pump inverter that combines IE5 premium-efficiency synchronous reluctance motors with advanced VFD technology. Featuring the top IES2 system energy efficiency rating, it delivers exceptional energy savings through energy-saving sleep mode and pre-sleep pressure boosting to minimize waste in low-load scenarios.

Intelligent Water Supply Solution

Designed for intelligent water supply applications, the MPD Series supports up to 8 pumps (1 master + 7 slaves) with multi-pump redundancy. With a built-in 14k-step PLC and perpetual calendar scheduling, it enables automatic pump quantity adjustment, cyclic load balancing, and flow estimation without external meters—perfect for residential communities, hospitals, and other scenarios with variable water demand.

Industrial Plants

Process water supply for manufacturing, food & beverage, and chemical processing. IES2 energy efficiency meets global green standards while withstanding harsh factory environments.

Municipal & Public Infrastructure

Water distribution for municipal networks, fire-fighting systems, and large public venues. Supports up to 8 pumps in parallel for large-scale applications.

Hospitality & Tourism

Water supply for hotels, resorts, and golf courses. Low-noise operation and energy-saving features provide reliable service without disturbing guests.

Agricultural Irrigation

Irrigation for crops, greenhouses, and livestock farms. Perpetual calendar scheduling and IP55 rating adapt to variable weather conditions and outdoor environments.

Frequently Asked Questions

Q1: Does this pump inverter comply with European electrical standards?

A1: Yes, the MPD series meets EU CE standards including EN61800-9-2 for energy efficiency and EMC directives. We provide full customs clearance documentation for smooth import processes.

Q2: Are the flange size and mounting dimensions compatible with American standard pipelines?

A2: Yes, the MPD series uses IEC-standard flanges that are fully interchangeable with ANSI-standard pipelines common in the US. Mounting options match most existing pump bases.

Q4: Can our electricians install this without professional training?

A4: Most electricians with industrial inverter experience can handle installation. Quick-connect fittings and printed wiring diagrams make the process straightforward with support available if needed.

Q5: Will the IP55 rating hold up against heavy rain and dust in outdoor installations?

A5: Yes, the IP55 rating means it's dust-tight and protected against low-pressure water jets. No extra enclosure is needed for outdoor installations when properly mounted.

Q7: What should I do when the LCD shows "Dry-run Protection"?

A7: Check for water in the tank or blocked inlet pipes. After fixing the water supply issue, press the "Reset" button. Adjust "Dry-run Delay" settings and enable "Low Water Level Alarm" for prevention.

Q9: How often does the pump inverter need maintenance?

A9: It's low-maintenance. Clean cooling vents every 6 months, check wiring connections, and replace cooling fan every 2 years if needed. The inverter lifespan is 8-10 years under normal use.
