EVERGROW EG250 Heavy-duty Centrifugal Pump

Innovative Structure Design

Equivalent to NOV Mission 2500 Supreme line pump design, and the full line of spare parts are 100% identical in all dimensions to Mission 2500 Supreme, Halco, SPD Baker, MCM, Double Life, and most popular brand pumps, completely interchangeable with other pumps currently on the market.

One-piece, Thicker, Stronger and Concentric Casing 

All EVERGROW EG250 pump casings are designed thicker than the conventional domestic pump casings, and the concentric casing eliminates vibration, turbulence, and cavitation which is caused by cut water in the conventional volute pumps, and it also can reduce the high bearing load and shaft deflection present in other designs at near shutoff flows.

Casing jack bolts allow the casing to be mechanically removed eliminating the need for pry bars or striking the casing during maintenance and eliminating damage to the casing and pedestal during disassembly.

Wear Pads

The casing provides a replaceable casing wear pad on 4x3x13 -10x8x14 models, to extend the life of the casing and allow the casing to be repaired at a lower cost by merely replacing the wear pads.

Wider, Semi Open Impeller

Compared with an open vane design, a semi-open impeller design could reduce the most of solids that enter the stuffing box, which could extend the life of the mechanical seal or packing and stuffing box. Available on pump sizes of 5x4x14 to 10x8x14.

2 1/2" Larger Heavy-duty Alloy Steel Shaft

Much larger pump shaft for heavy-duty performance, min. deflection and increased life of packing and mechanical seal; and the replaceable hook type shaft sleeve is easily replaced in the field without removing the shaft, which prevents the shaft wear and prolongs the shaft working life. A ceramic coated shaft sleeve is for option.

Long Life Cost-Effective Mechanical Seal

The mechanical seal allows for near zero leakage. Single tungsten carbide vs. tungsten carbide mechanical seal is the factory standard, which is highly abrasive resistant in PH value of 7-14. And silicon carbide vs. silicon carbide mechanical seal is recommended for a lower PH level. Both types are lubricated by the transferring fluid and required the pump to remain primed during operation. EVERGROW also offers a more economical option, packing rings to address the leakage.

High-quality, Advanced Front and Rear Bearings

The outboard bearing is a duplex set of angular contact bearings with high thrust load capabilities and zero end play, and the front or inboard bearing is a single row roller bearing with high radial load capabilities to replace the previous double row bearing. Advanced front and rear bearing designs reduce both radial and thrust loads. Grease lubrication is the factory standard. Oil lubrication is recommended for pump speed over 2400rpm, upon request.

Easy Removal Stuffing Box

Dual stuffing box bolts are positioned 180 degrees apart to hold the stuffing box in position during casing removal. To remove just one bolt to remove the stuffing box to access the casing and stuffing box chamber for the convenient replacement of shaft sleeve or mechanical seal installation. Grease lubrication or to flush the internal flushing 5 standard rings of packing w/ a lantern ring can be operated from the tapped opening on the stuffing box.

Solid Frame Pedestal

The solid frame base provides strong support to the heavy-duty pump performance and is replaceable with other popular brand pumps of the same pedestal size.

Various Fluid End Material Selections

The hard iron fluid end is the factory standard, but we also provide various fluid end materials of stainless steel(304,316), aluminum bronze, high chrome alloy iron, and hardened hard iron(carbide coating) for a variety of applications. High chrome alloy iron material is specifically for high abrasion resistance required, which provides greater wear resistance and higher strength in the casing, stuffing box, and impeller, hardness to be HB600, even 3 times wear resistance than that of hard iron; and carbide coating is about 2 times harder than that of hard iron but at an economic cost.

Multiple Applications

EVERGROW EG250 heavy-duty centrifugal pump can be used in a multitude of applications from handling abrasive cement, and drilling fluid in the oil & gas industry, also disposal of waste, and Mine de-watering, seawater, etc.

Same Power End

Model of 3x2x13 to 10x8x14 with the same power ends to reduce greatly spares inventory.

Centrifugal Pump Skid Packages

For the convenience of our valued customers, EVERGROW also offers its pumps mounted on skid packages, coupled with electric motors, diesel engines, or hydraulic motors. Unitization services are offered as flexible coupling connect, belt driven, or close coupled and can be designed for mounting in a horizontal or vertical position, and wired with starters if so desired. The equipped motor is IP65 explosion-proof motor proved by CNEX or IEC. Sizes from 3x2x13 to 10x8x14.

Painting and Packaging

All EVERGROW standard pumps are painted with 3 layers of quality paint, a primer: Zinc, Second Coat: Epoxy base, a Top coat: High build polyurethane, and also accept customized painting colors at an additional charge. All parts are properly packaged to protect during shipping, and a clear mark or label will be indicated on the packaging for easy identification.

Performance Testing

All EVERGROW pumps before being released from the factory are performed in-house hydrostatically test at no charge, we also accept third-party testing if our customer required additional charges.
