Product Description

BETTER has been engaged in designing and manufacturing Solid Control Equipments
and Mission style centrifugal pumps for the fluid handling system over 15 years. BETTER SB2500 Centrifugal Pump with heavy duty construction has highly equivalent design as Mission Supreme 2500 line and MCM250 series, which offers a wide selection for a variety of routine, demanding, wide range of flow rate, abrasive and corrosive application and reduces downtime and total cost.

Mission 2500 Supreme is improved from Halco 2500, with all the feature of Mission Magnum I and also its unique design to suit for most application. Both separate pump lines own same operating and dimensional design. We also introduced this revolutionary design in order to provide a more competitive choice for all operators and contractors in today's aggressive applications.

BETTER SB2500 Heavy-duty Centrifugal Pump

Features
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 of BETTER SB2500 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 eliminates damage to the casing and pedestal during disassembly.
Wear Pads
Casing provides with replaceable casing wear pad on 4x3x13 -10x8x14 models, to extend life of casing and allow the casing to be repaired at a lower cost by merely replacing the wear pads.
Wider, Semi Open Impeller
To compare with open vane design, 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 size 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, and which prevent the shaft wear and prolong the shaft working life. 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 type is lubricated by the transferring fluid and required the pump to remain primed during operation. BETTER also offer more economical option, packing rings to address the leakage.
High quality, Advanced Front and Rear Bearings
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 design reduces 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 into 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 a strengthen support to the heavy-duty pump performance, and replaceable with other popular brand pumps by same pedestal size.
Various Fluid End Material Selections
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, hardened hard iron(carbide coating) for a variety of applications. High chrome alloy iron material is specifically for high abrasion resistant 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
BETTER SB2500 heavy duty centrifugal pump can be used in a multitude of applications from handling abrasive cements, drilling fluid in the oil & gas industry, also disposal waste ,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, BETTER 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 BETTER standard pumps are painted with 3 layer of quality paint, primer: Zinc, Second Coat: Epoxy base, Top coat: High build polyurethane, and also accept customized painting color at an additional charge. All parts are properly packaged to protect during shipping, and the clear mark or label will be indicated on the packaging for easy identification.

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