Series 30 | Industrial Liquid Centrifugal Pump

The MP Pumps Series 30 is a precision‑engineered end suction centrifugal pump designed to deliver reliable hydraulic performance in demanding operating environments. Its close‑coupled layout, compatible with standard NEMA “C”‑face motors, ensures both mechanical rigidity and simplified system integration, reducing alignment concerns and minimizing installation time. The pump is offered in cast iron or bronze construction, allowing engineers to match material compatibility to the chemical and physical properties of the handled liquid. All externally exposed fasteners are manufactured from stainless steel, which significantly enhances corrosion resistance and supports longer operational life under harsh environmental conditions. 

At the core of the hydraulic design is a 3.25" (82.55 mm) semi‑open impeller, dynamically balanced to maintain smooth operation even at high rotational speeds. This balancing minimizes vibration levels, which contributes to extended bearing life both in the pump and the motor to which it is coupled. The semi‑open impeller geometry allows the Series 30 to handle solids up to 0.27" (7 mm), enabling operation with mildly contaminated liquids without performance degradation. The pump is capable of delivering flow rates up to 45 GPM (10.2 m³/h) and total dynamic head up to 40 feet (12 meters), making it suitable for both transfer and circulation duties across multiple application segments. 

The Series 30 is equipped with a high‑quality mechanical seal featuring carbon, ceramic, and Viton components as standard. This sealing configuration provides balanced chemical resistance, thermal stability, and longevity under typical agricultural, industrial, and commercial fluid conditions. For applications requiring specialized chemical compatibility or exposure to more aggressive liquids, alternative seal material combinations are available upon request, enabling precise tailoring to process requirements. The seal is self‑adjusting, minimizing the likelihood of leakage over time and reducing the need for frequent maintenance interventions. 

The pump’s PumPAK® option allows end users to mount the hydraulic assembly directly onto 56C‑frame motors within minutes, offering a modular approach that simplifies replacement and system customization. The close‑coupled configuration removes the need for couplings, guards, or alignment tools, reducing both system footprint and installation cost. With its ability to accommodate motor power levels up to 1 HP (0.74 kW), the Series 30 provides scalability across a range of flow and pressure requirements, making it a flexible solution for OEMs and equipment integrators. Overall, the Series 30 combines corrosion‑resistant construction, precision hydraulic engineering, and simplified mechanical integration into a robust and versatile pump platform. Its combination of material options, seal configurations, solid‑handling capabilities, and compatibility with standardized motor frames makes it an optimal choice for operators seeking a dependable, easy‑to‑service centrifugal pump for continuous or intermittent operation across agricultural, commercial, industrial, and OEM environments.
