EG-250 Centrifugal Pump 5x4x14 — Reliable Solution for Mud Circulation and Solid Control

The EG-250 Centrifugal Pump 5x4x14 is a robust, field-proven centrifugal pump designed for drilling mud circulation, solids control feeding, and abrasive slurry handling. This model is fully interchangeable with Mission Magnum I 5x4x14 / MCM 250 series centrifugal pumps, making it an ideal replacement option for oilfield operators seeking performance compatibility and cost efficiency without modifying existing systems.

With a rated capacity of 80–120 m³/h and a head range of 24–28 meters, the EG-250 Centrifugal Pump 5x4x14 delivers stable flow and reliable pressure under continuous-duty conditions. The pump is equipped with a 14-inch impeller and is commonly driven by 18.5 kW, 22 kW, or 30 kW motors, operating at 1450 rpm or 1750 rpm, allowing flexibility to match different site power requirements.

Designed for Abrasive and High-Solid Fluids

The EG-250 Centrifugal Pump 5x4x14 features an open impeller design with wide vanes and a tangential suction profile. This hydraulic structure promotes smoother flow patterns, reduces turbulence, and improves handling of abrasive drilling muds and slurry fluids. As a result, internal wear is minimized, and pump efficiency is maintained over longer operating cycles.

To further enhance durability, the pump casing is manufactured with increased wall thickness to resist erosion and corrosion. Available fluid-end materials include high-chrome alloy, hard iron, cast iron, and stainless steel, allowing the EG-250 Centrifugal Pump 5x4x14 to be configured for different fluid characteristics and operating environments.

Strong Mechanical Structure and Easy Maintenance

The power end of the EG-250 Centrifugal Pump 5x4x14 is engineered for long service life. A larger, stronger shaft reduces deflection under load, while long-life bearings support stable operation in high-demand conditions. A replaceable shaft sleeve is installed in the packing wear area to protect the shaft and simplify routine maintenance.

In addition, the pump is equipped with a replaceable stuffing box cover, supporting both packed stuffing box and mechanical seal configurations. This modular design allows operators to adapt the EG-250 Centrifugal Pump 5x4x14 to different sealing preferences while reducing downtime and spare-part costs.

Flexible Installation and Standardized Design

The EG-250 Centrifugal Pump 5x4x14 can be supplied as a bare shaft pump or unitized with electric motors, diesel engines, or hydraulic motors. Horizontal, vertical, and close-coupled configurations are all available, making the pump suitable for various skid packages and space-limited installations.

With an approximate pump weight of 525–615 kg (depending on configuration) and compact dimensional options, this model integrates easily into existing mud systems. As part of the standardized EG-250 pump range (from 3x2x13 to 10x8x14), it shares common power-end components, helping reduce spare-parts inventory and simplify maintenance planning.

Typical Applications

The EG-250 Centrifugal Pump 5x4x14 is widely used for:

Drilling mud circulation

Solids control feeding pumps

Fresh water and seawater transfer

Abrasive slurry and industrial fluid handling

Its proven structure, interchangeable design, and flexible configurations make the EG-250 Centrifugal Pump 5x4x14 a dependable choice for drilling, production, well servicing, and general oilfield operations.
