FMX 75 | 3/4" Self Priming Pump

The FMX 75 is a high‑performance self‑priming centrifugal pump engineered for demanding applications that require exceptional durability, chemical resistance, and dependable operation. Designed and manufactured by MP Pumps, this 3/4" x 3/4" stainless steel pump is widely used across marine, industrial, agricultural, commercial, and OEM environments. Its robust construction, combined with advanced hydraulic performance, ensures reliable fluid handling even in harsh and corrosive conditions.

 

*The online store fulfills orders only within the USA.

Product Overview

The FMX 75 is built entirely from 316 stainless steel, offering superior corrosion resistance and structural integrity when exposed to saltwater, chemicals, and aggressive process fluids. Its semi‑open 316 stainless steel impeller ensures excellent solids‑handling capability and consistent hydraulic performance, while maintaining smooth flow characteristics.

A key benefit of the FMX 75 is its self‑priming capability, allowing it to achieve a suction lift of up to 12 ft (3.6 m) at 3450 RPM. This makes it a highly effective solution for installations where the pump must handle fluids below pump centerline or operate in intermittent‑flow conditions.

The pump features an industry‑standard carbon/ceramic/Viton bellows‑type mechanical seal, ensuring leak‑free operation and compatibility with a wide range of industrial fluids. Special seal options are available for more demanding environments.

The FMX 75 is designed for installation versatility, equipped with 3/4" NPT suction and discharge ports and a 1/8" NPT fill port. It is available in multiple drive configurations, including close‑coupled AC and DC motors. For marine installations, ignition‑protected motors compliant with ISO 8846 standards are available, along with ABS Type Approval for enhanced safety and regulatory compliance.This pump’s compact, rugged design and stainless‑steel construction make it ideal for applications requiring durability, reliability, and performance in corrosive or washdown‑intensive environments.
