Smart Turner Pumps ANSI pumps are ideally suited to plant service and chemical process applications where continuous,
reliable operation is essential, whether the fluid is clean, dirty, corrosive or abrasive. Features: Pumps:
Back pullout construction to ANSI B73.1 dimensional standards. Top centre line discharge and casing feet ensure maximum rigidity and stability, while Smart Turner Pumps quality and precision ensure accurate fits and clearances.
Casings:
A radically split cast volute with integral suction cover, ruggedly designed with generous allowance for abrasion and corrosion. 125/1 50 p.s.i. ANSI flat faced flanged connections are standard. 250/300 p.s.i. flat faced flanges are an option.
Impeller:
Cast in one piece, the fully open impeller is trimmed to the exact diameter required and is factory balanced. The heavy section of the impeller provides excellent wear and corrosion allowance, and the partial rear shroud provides maximum support for the blades. Rear pump out vanes provide axial hydraulic balance and low, but normally positive, stuffing box pressure. The pump out vanes are recessed into the stuffing box cover to maintain pump out efficiency if axial adjustment is made.
Micro-Adjustment:
All ANSI pumps have a provision for impeller clearance adjustment. This adjustment between the impeller and the casing moves the impeller toward the suction wall of the casing. This facilitates improvements to losses in pressure due to normal wear.
Stuffing Box Cover:
A heavy one piece casting with rabbeted fit to the casing for positive alignment. The deep bore will accept a wide range of packings or mechanical seals, tapered boxes can also be accommodated.
Gland: Split for packed stuffing boxes and solid for mechanical seals, the gland can be provided in a variety of arrangements to suit the application. Gaskets:
All gaskets are fully contained. Shaft:
Precision machined high quality alloy, normally fitted with a renewable sleeve, and oversized to minimize deflection to ensure smooth operation and maximum packing or seal life. Sleeve:
A precision machined, stainless steel, hook sleeve with an "0" ring seal against the impeller. A solid shaft without sleeve can be provided. Bearings:
Antifriction bearings are generously sized for longer life, with a double row thrust bearing for minimum end play. Grease or oil lubricated arrangements are available. Grease is recommended for most services as being simpler and more reliable. Bearings are protected by seals at both ends of the housing.
Bearing Housing:
A rigid casting with precisely machined bores and rabbet fit to the adaptor to ensure concentricity and alignment with the stuffing box cover, casing, and rotating element. The housing is supplied with micrometer adjustment, for easy impeller adjustment.
Adaptor: A rigid casting with integral gland drip reservoir, precision machined to ensure rigid and consistent alignment between bearing housing and liquid end. Interchangeability:
All pumps utilize one of only three bearing housings.
Pumps with the same bearing housing have fully interchangeable shafts, sleeves, bearings, packing, seals, glands, and hardware resulting in an efficient parts inventory at both the factory and the
customer. Tests: All pumps are hydrostatically tested to 50 p.s.i. above the maximum casing design pressure. |
Optional Equipment Base:A rigid channel or fabricated base can be provided to our standard for electric motor drives.
Special bases can be provided and can incorporate grout holes, drip rims, and other features. Guard:
A coupling guard to our standard can be mounted on the baseplate. Special guards can be accommodated. Flexible Coupling: For normal duty our current standard is provided when a coupling is ordered. However, couplings of almost any style or manufacture can be accommodated. Motors:
An electric motor or other driver can be provided. Coolers: A cooling coil can be fitted to oil lubricated bearing housings for operation at elevated temperatures. No
cooling is required for liquid temperatures below 350º F (177ºC). Note: standard grease lubrication is good to liquid temperatures of at least 250ºF (120ºC). |
