Series 80 - Hydraulic | Industrial Liquid Centrifugal Pump

The Series 80 Hydraulic pump is engineered as a heavy‑duty, end‑suction centrifugal pump designed to provide stable, high‑efficiency operation in challenging environments across industrial, agricultural, marine, and OEM applications. Its hydraulic and mechanical design emphasizes durability, precise fluid handling, and compatibility with variable hydraulic drive systems.

At its foundation, the pump is built from robust cast iron, selected for its exceptional mechanical strength and ability to withstand high pressures and thermal fluctuations. This structural rigidity helps the pump maintain precise internal tolerances even during continuous‑duty operation, reducing internal leakage and improving overall hydraulic efficiency. Stainless‑steel fasteners further reinforce the pump’s resistance to corrosion and environmental exposure, making it suitable for harsh operating conditions such as marine atmospheres or agricultural chemical environments. 

At the center of the hydraulic system is the dynamically balanced enclosed impeller, measuring 5.9″ (149.86 mm) in diameter. This enclosed design minimizes recirculation losses and promotes smoother, more uniform hydraulic flow inside the volute. As a result, the Series 80 Hydraulic can achieve flow rates up to 145 GPM (32.9 m³/h) and heads reaching 370 ft (112.7 m), maintaining strong performance even at higher system pressures. Dynamic balancing significantly reduces vibration and bearing load, improving operating smoothness and extending service life—especially important in mobile machinery or onboard marine systems. 

Sealing performance is maintained through a self‑adjusting mechanical seal made from carbon, ceramic, and Viton components. This combination ensures durability against thermal expansion, pressure variation, and chemical exposure. The seal automatically compensates for wear, helping maintain consistent sealing pressure over time and reducing maintenance requirements. Its material set enables reliable operation with a broad range of liquids encountered in industrial transfer, agricultural spraying, or marine circulation. 

One of the defining strengths of the Series 80 Hydraulic is its compatibility with multiple hydraulic motor configurations. The pump can be equipped with 0.37, 0.45, or 0.58 cubic‑inch displacement motors (6.06 cm³, 7.37 cm³, 9.50 cm³), allowing operators to match pump performance precisely to the available hydraulic power. These systems accommodate hydraulic fluid flows up to 15 GPM (3.4 m³/h) and hydraulic pressures up to 2500 PSI (172 bar), providing exceptional flexibility for installations where hydraulic supply conditions vary by machine or system. The integration of these motors eliminates the need for electric motors or engine‑driven couplings, making the pump suitable for environments requiring variable‑speed control or where electric drives are impractical. 

The Series 80 also offers a solids‑handling capability of up to 0.11″ (2.8 mm), making it suitable for liquids that may contain small particulates or suspended solids typical in agricultural or industrial applications. The pump features a 1½″ NPT suction and 1¼″ NPT discharge connection layout, ensuring broad compatibility with standard industrial pipe fittings and hydraulic equipment manifolds. This simplifies integration into new system builds as well as retrofit applications. 

Overall, the Series 80 Hydraulic integrates rugged construction, refined hydraulic engineering, reliable sealing technology, and versatile motor options. The result is a high‑performance centrifugal pump capable of consistent, efficient operation under demanding conditions, backed by long service life, stable performance curves, and minimal maintenance requirements—attributes that make it a standout choice for operators seeking durability and flexibility in critical fluid‑handling applications.
