Features:
One-piece, Thicker, Stronger and Concentric Casing
All of BETTER SBM 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.
Wider, High Efficient, Open Vane Impeller
The open vane design eliminates re-circulation, which occurs in closed impellers; and the back vanes are the same curvature as the front vanes, which is more tangential to the circumference of the suction to reduce turbulence.
To remove the metal between the vanes, and to provide partial shrouds for max. vane support, the reduced unbalanced forces brings a much lower axial thrust to min. and improved bearing life; and the back pump-out vanes reduce the concentration of solids at the stuffing box and lower the pressure on the stuffing box to prolong its life.
Wider impeller design and larger distance from the tip of vanes to the casing allowed the fluid leaving impeller to blend with re-circulating fluid, it greatly reduce the casing's abrasive wear and eliminate scrubbing action.
The impeller is screwed onto the shaft with o-ring sealing, and the impeller anti-loosening device prevents the impeller loosening if the pump runs backwards during startup and inspection of motor direction.
Smooth impeller eye deign for minimum turbulence and high efficiency.
External adjustment of impeller distance is available to extend pump life.
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.
