About this file
This is a technical specification document for self-priming trash pumps submitted as Exhibit F to the City of Austin's Request for Proposals (RFP 5000 BYS3046) for maintenance and repair services of pond pump and irrigation systems. The document details Rotech Pumps' SPT/SXT and SPU/SXU series of frame-mounted, self-priming centrifugal pumps designed for handling solids-laden liquids and slurries. Available in discharge sizes ranging from 2 inches to 12 inches, these pumps feature superior solid handling capabilities with impellers designed to handle solids up to 3 inches in diameter depending on model. Key specifications include multiple drive and coupling options compatible with NEMA, IEC motors, and diesel engines; material options including cast iron, stainless steel variants, and specialty alloys; and interchangeable components between SPT and SXT series. The pumps operate across RPM ranges of 650 to 2,900 depending on size, with detailed hydraulic performance curves, dimensional data, and maintenance specifications provided. Design features emphasize ease of maintenance with removable rotating assemblies, trash covers, dual bearing protection with atmospheric barriers and dual lip seals, and automatic re-priming capability without check valves.
The document includes comprehensive dimensional tables with lettered reference points (A through S) for both SPT/SXT and SPU/SXU pump series, enabling contractors to verify pump specifications and ensure proper installation within the City's water quality and retention/irrigation pond systems. A detailed comparison table distinguishes parts interchangeability between SXT and SPT models, identifying common components such as wear plate assemblies and seal components alongside non-interchangeable items including volute casings and impeller shafts. Contact information for Rotech Pumps' headquarters in Mississauga, Ontario, and Odessa, Texas is provided for technical inquiries and pump selection assistance. This specification document serves as a reference standard for contractors bidding on the maintenance and repair contract to ensure compliance with equipment requirements and proper procurement of replacement parts for the City's existing pond pump infrastructure.

Key Advantages
• Superior Solid Handling
• Self Priming
• Easy Maintenance
Drive Options
Can be coupled with standard NEMA & IEC motors. No special motor required. Also can be coupled with diesel engine.
Coupling Options
• Direct Coupled
• Belt – Pulley Driven
Impeller Options
Two-vane, ductile iron, semi-open solids-handling impeller handles up to 75 mm (3”) diameter solids, depending on pump model. Pump out vanes on the impeller shroud reduce foreign material buildup behind the impeller and reduce pressure on seal and bearings.
Material Options
Cast Iron, ADI, CS, 304SS, 316SS, CD4MCUN, Alloy20, Hastelloy-B & C
Available Discharge Sizes
2”, 3”, 4”, 6”, 8”, 10” & 12”
Sealing Option
SELF-PRIMING TRASH PUMPS
Rotech Pumps presents a range of Self-Priming Centrifugal.These pumps are economical & offer trouble-free operation in handling solids laden liquids and slurries. Pump features a large volume design which allows them to re-prime automatically in a completely open system without the need of suction or discharge check valves. And this is workable with the pump only partially filled with liquid and completely dry suction line. Pump can handle up to 3” spherical solids, depending on pump models. In case pump shafts or bearings need service, the entire rotating assembly can be removed without disturbing pump casing or pipelines.
Design Features
Available in Tc/Tc/Viton mechanical seal to handle abrasive liquid and sewage, Industrial waste etc.. Custom designed seal to handle corrosive chemical like Keton, Xylene, Tolulene
Trash Design
Trash cover for easy maintenance without disturbing pipeline
Dual Bearing Protection
An atmospheric barrier along with two lip seals provide additional protection of the pump bearings. This unique design also allows for quick and easy external monitoring of the bearing cavity (not available on 2” models).
Removable Rotating Assembly
The entire rotating assembly can be removed without disturbing the pump volute or piping. Pusher bolt holes are provided to assist with removal. This allows for quick and easy installation of a spare rotating assembly, resulting in less downtime.
