MDX | Sealless Centrifugal Circulator Pump

The MDX 1" x 1" Centrifugal Transportation Circulator Pump from MP Pumps is engineered for high-performance fluid handling in demanding environments. Designed with a sealless, magnetically-driven system, it delivers flows up to 25 GPM (97 LPM) and pressures reaching 20 feet (6 m) of TDH. Available with 12V or 24V DC brushless motor options, the MDX offers outstanding versatility and reliability.

Built from durable aluminum with a 2.5" semi-open stainless steel impeller, the MDX pump is perfectly suited for agricultural, commercial, industrial, marine, OEM, and transportation applications. Its integrated, adjustable mounting base and weather-resistant motor enclosure ensure easy installation and long-term operation, even in harsh conditions. Designed for ambient temperatures up to 200°F (93°C) and fluid temperatures up to 220°F (104°C), the MDX is your solution for consistent, efficient fluid circulation.
