Pumps, Motors & Services Safe, reliable, and economical solutions for the nuclear industry

Supporting the nuclear industry as an OEM for over 60 years. At Hayward Tyler, we have been active in the nuclear industry since the mid 1950’s, when we supplied pumps to Calder Hall, the world’s first full-scale nuclear generating plant. As a leader in performance-critical pumps and motors, we continue to support all generations of nuclear power plants across the globe. We are committed to the needs of the nuclear industry and are continuously looking at ways to deliver value to our customers. years experience in nuclear industry of nuclear power stations in North America operate with...

Our Quality Program Our in-house quality assurance program meets NQA-1, NCA4000 and NRC requirements 10CFR50 Appendix B and 10CFR21 with regular audits from individual utilities as well as NUPIC (consisting of international representatives). Commercial Grade Dedication Our Commercial Grade Dedication program provides us flexibility in supplying difficult-to-source materials. Through this program, we provide bottom-line value to our customers and combat supply chain obsolescence issues. Safety-Related Equipment We can supply ASME Section III, Division 1, Class 1, 2 or 3 equipment, including...

Vertical Turbines Hayward Tyler manufacturers vertical, centrifugal single or multistage pumps for applications requiring low NPSH, medium head and medium capacity. We can supply pumps for “Safety” and “Non-safety” related applications. The VS range was designed specifically for the nuclear industry, offering three different impeller types. Each impeller type offers a different head-capacity curve ranging from steep to a flatter curve, depending on system requirements. With decades of operating experience, Hayward Tyler is consistently providing service and technical support for nuclear...

Vertical Axial & Mixed Flow Pumps Ideal for applications where large flow capacities at relatively low heads are required, or when suction lifts are too great for horizontal pumps. Engineered to fit customer requirements, these pumps feature a number of hydraulic designs to provide variation in the capacity curve characteristics, from a steep to a flat curve. Operation Parameters Discharge Sizes g Cooling Water Make-up Double Suction Single-stage horizontally or radially split pumps using a double suction impeller, this rugged design is particularly suited for hazardous, safeguard-operating...

PRODUCTS SEALLESS PUMPS Canned Motor Pump Canned motor pumps offer a combined pump and motor on a common shaft wrapped in a pressure boundary. This eliminates the need for mechanical seals, which removes the chance of a process fluid leak. These are ideal for applications where leakage cannot be tolerated or minimal maintenance is required. This is particularly true in nuclear applications where ALARA principles apply. Operation Parameters MOTOR Design Pressure Design Temperature *Higher available upon request Applications g Reactor Water Clean Up (RWCU) g Spent Fuel g Boron System g...

Wet Stator Unit Vertical pump with an integrated wet wound motor. The pump and motor are designed for the same internal pressure so there is no need for a dynamic mechanical seal. Ideal for high inlet pressure and temperature applications. Operation Parameters MOTOR Applications g Reactor Water Design Pressure Design Temperature g Reactor Circulating Pump (RCP) g Pressure High Circulation End Suction The N3 is an end suction, vertically split, single stage pump. It has a back pull out design, with foot or centerline mounting arrangement with a closed or semi-open impeller. It has a...
