Hydronic and Pump Accessories
Hydronic and Pump Components for Peak System Performance
Southeast Pump & Equipment provides hydronic accessories that form the backbone of efficient, balanced, and reliable mechanical systems. Whether you’re designing for a hospitality high-rise, a data center, or a public aquatics facility, our proven product lines and engineering support help you build better systems from the ground up.
Suction Diffusers
Brands: Grundfos, Metraflex, American Wheatley
Suction diffusers combine multiple functions into a single compact component installed at the suction side of a pump. These units:
- Strain debris from entering the pump, protecting impellers and seals
- Condition flow by reducing turbulence and creating a laminar inlet profile
- Save space and reduce fittings by eliminating the need for separate strainers, long elbows, or straight pipe runs.
American Wheatley models are available with stainless steel screens, optional blowdown ports, and integral support pads to simplify installation.
Applications: Pump rooms, chilled water systems, heating loops, closed-loop HVAC circuits.
Triple Duty Valves AKA Multi-Purpose Valves
Brands: Grundfos, American Wheatley
Manufacturers engineer these multi-function valves to combine:
- Check valve (to prevent reverse flow)
- Isolation valve (for maintenance and service)
- Flow balancing valve (to regulate system flow with accuracy)
By integrating all three functions into a single body, Triple Duty Valves streamline piping configurations, minimize pressure drop, and cut installation costs. We stock American Wheatley models in multiple sizes and pressure ratings, including options with readout ports for precise flow measurement and system diagnostics.
Applications: Booster pump packages, hydronic risers, primary-secondary loops, commercial HVAC systems.
Expansion Tanks
Brands: Grundfos, American Wheatley, Elbi
Expansion tanks are crucial for managing pressure fluctuations resulting from thermal expansion in closed-loop systems. We offer:
- Bladder-style tanks with replaceable or fixed membranes
- ASME-rated tanks for high-pressure commercial applications
- Vertical or horizontal configurations for flexible design integration
Our ELBI expansion tanks are designed for long service life, featuring corrosion-resistant liners and a factory pre-charge. American Wheatley tanks meet or exceed industry standards and are available with system connections for pressure relief valves or air separators.
Applications: Chilled water loops, heating systems, glycol-based circuits, closed-loop geothermal.
Chilled Water Buffer Tanks
Brands: Grundfos, American Wheatley, Delta
Buffer tanks stabilize system temperature and reduce chiller or heat pump cycling by adding thermal mass, thereby minimizing energy consumption. They:
- Increase system volume to meet minimum run times
- Prevent rapid cycling, which can reduce equipment life
- Ensure temperature stability during low-load conditions
Our chilled water buffer tanks are available in a wide range of sizes, featuring factory-installed insulation, temperature sensor ports, and lifting lugs. These tanks are ideal for variable load systems where thermal inertia is key to operational efficiency.
Applications: Commercial chiller plants, VRF/VRV systems, data centers, educational and healthcare facilities.
Epoxy Lined Water Storage Tanks
- FDA-approved epoxy lining for potable water applications
- ASME Section VIII construction with U-Stamp certification
- Vertical configurations for efficient mechanical room layouts
- Long service life with reduced maintenance requirements
Control Panels
Brands: Cougar Systems
We design our UL-listed custom Cougar Systems control panels to provide plug-and-play control of sump pump systems, condensate return systems, level control, filtration packages, or booster sets. Features include:
- VFD integration for energy-efficient pump control
- BMS/Modbus communication for seamless building automation integration
- Touchscreen HMIs for intuitive operation and diagnostics
- Alarm monitoring and remote support capabilities
We offer design support for single-point responsibility solutions, whether you’re controlling a domestic booster system, a closed-loop chilled water plant, or a packaged skid.
Applications: Effluent Sump, Sewage, Elevator Sump, Hospitality facilities, mechanical rooms, water treatment skids, and fountain control systems.

Coalescing Air and Dirt Separators
SweepCLEAR® is a patented filter of SS Wire Mesh Media Coils that, when inserted into an air separator, creates a low-cost and high-performance air and dirt separator. Designed to enhance system efficiency, SweepCLEAR® dramatically improves the removal of entrained air and suspended particulate from hydronic systems. Its coalescing action forces micro-bubbles to merge into larger pockets that are easily separated and eliminated, reducing noise, corrosion, and pump wear.
Easy to install and retrofit, SweepCLEAR® delivers reliable performance with minimal maintenance. Optimize your system’s longevity and energy efficiency with a coalescing air and dirt separator engineered for robust operation.
Applications: Commercial, industrial, and residential
