WEINMAN PUMPS

Weinman, a brand of Crane Pumps & Systems, manufactures centrifugal pumps, split-case pumps, vertical inline pumps, and condensate return equipment for HVAC, commercial, municipal, and industrial water systems.

Great Lakes Pump & Supply provides Weinman pumping equipment and related system components for chilled and hot water circulation, cooling towers, boiler service, pressure boosting, and general water-transfer applications.

Weinman Pump Products for HVAC and Water Service

Weinman Pumps

Weinman pumping equipment serves a range of building and industrial water-system requirements, from general circulation to higher-capacity water transfer and pressure boosting.

End-suction centrifugal pumps support conventional water circulation and transfer. Vertical inline pumps accommodate installations where piping alignment and available space are important. Split-case pumps provide configurations for larger-capacity systems, while condensate return equipment collects and returns recovered water from compatible heating processes.

The Weinman product range also includes pump accessories and NSF 61/372-certified split-case options for applications involving drinking water.

Equipment selection depends on the required flow rate, total dynamic head, liquid temperature, piping configuration, and system operating conditions.

Pumps and Pump Systems

End-Suction Centrifugal Pumps

Weinman end-suction centrifugal pumps support general water circulation, industrial liquid transfer, and commercial or municipal pumping applications. Available product families include close-coupled and frame-mounted configurations, with different hydraulic capacities and service arrangements.

Common applications: Chilled and hot water circulation, HVAC systems, cooling towers, industrial processes, municipal water service, and compatible irrigation systems.

Vertical Inline Pumps - CV Series

Weinman CV Series vertical inline centrifugal pumps are designed for circulation applications where suction and discharge connections are arranged on the same centerline. This configuration supports direct pipeline installation and can reduce the floor space required by conventional pump arrangements.

Common applications: Hydronic heating and cooling, HVAC circulation, commercial building systems, and industrial liquid circulation.

Split-Case Pumps - L / LVM / JD Series

Weinman split-case pumps provide configurations for larger-capacity water-transfer and circulation requirements. The L Series includes horizontally mounted single-stage pumps, the LVM Series provides vertically mounted configurations, and the JD Series addresses multistage, higher-head pumping requirements.

Common applications: General water service, municipal water transfer, domestic water boosting, chilled and hot water circulation, and compatible boiler feed or pressure-boosting systems.

Condensate Return Systems

Weinman condensate return units are designed to collect and automatically return hot condensate from radiators, heating coils, and similar equipment to compatible boiler systems. These packaged systems include receiver tanks, pump equipment, and controls.

Common applications: Steam-heating condensate recovery, boiler condensate return, commercial heating systems, and industrial condensate collection.

Pump System Components

Suction Diffusers

Weinman suction diffusers are installed on the suction side of compatible centrifugal pumping systems. They combine functions associated with suction strainers and piping transitions, helping reduce the space needed for certain pump installations.

Common applications: HVAC circulation systems, industrial water systems, commercial pump installations, and compatible centrifugal pump suction piping.

TD Valves

Weinman TD valves combine several discharge-side functions in one component, including shutoff, check-valve operation, and flow balancing. These components are used in compatible hydronic and water-circulation systems where flow control and backflow prevention are important.

Common applications: HVAC pump discharge piping, chilled and hot water circulation, industrial water systems, and building mechanical equipment.

Potable Water Pump Options

NSF 61 / 372 Split-Case Pumps

Weinman-Deming NSF 61/372-certified split-case pump configurations are designed for applicable drinking-water systems. These certifications address material-related requirements for equipment in contact with potable water.

Common applications: Potable water distribution, domestic water boosting, municipal drinking-water systems, and compatible clean-water circulation.

The required certification, approved materials, operating conditions, and specific pump configuration should be confirmed when selecting equipment for potable water service.

Selecting a Weinman Pump for Your Application

Selecting a Weinman pump begins with the required flow rate, total dynamic head, operating temperature, liquid characteristics, and available installation space.

End-suction pumps are appropriate for many conventional circulation and water-transfer applications. Vertical inline pumps may be useful where equipment must fit within an existing piping arrangement, while split-case pumps provide options for larger-capacity water systems and higher-head requirements.

Condensate return systems serve a different purpose by collecting and transferring recovered condensate. Receiver capacity, liquid temperature, control requirements, and pumping conditions affect system selection.

Suction diffusers and TD valves are supporting system components rather than standalone pumps. Their compatibility depends on the pump arrangement, piping dimensions, pressure requirements, and operating conditions.

For potable water applications, the specific pump configuration and applicable NSF 61/372 certifications must also be considered.

When evaluating replacement equipment, the existing manufacturer and model number, pump curve, motor specifications, connection sizes, mounting arrangement, and operating conditions can help identify suitable alternatives.
