High-Head Circulation Pumps for Water, Coolants, and Oil

Propel liquid higher and farther than standard circulation pumps. They're commonly used with chillers, heat exchangers, and boiler feed systems. The motor is open dripproof (ODP) for use in clean, dry, and well-ventilated environments. Pumps are gravity fed and require an elevated liquid source to fully fill the pump before turning on. Do not run dry or use with solids.
Note: If flow control is needed, place valves or reducers on the discharge side; never restrict the inlet of a pump with a valve or reducer.

Precision Liquid Chillers


Protect your most temperature-sensitive equipment from overheating. These chillers keep liquids within 0.18° F of the temperature you set. Far more advanced than basic chillers—which are accurate within a few full degrees—they’re even precise enough for use in medical imaging machines. Fill these chillers with distilled water or glycol solutions, and an internal pump moves the liquid out to your equipment and back in a continuous loop. They’re often used with spot-welding systems, molds, lasers, and X-ray diffraction equipment. Use the built-in keypad to manually set the temperature, or connect an external controller of your own to automate temperature changes. View the set temperature, alerts, and other information on the LED display.
120V AC chillers automatically replace their own filter, using a roller to swap in a fresh filter on a set schedule. Adjust the schedule to suit your application. A UV light system prevents algae and other bacteria growth, keeping the cooling liquid clean.
240V AC chillers have a bypass valve knob to control the chiller’s flow rate and pressure, which can affect the temperature of your liquid and how efficiently these coolers run.

Benchtop Liquid Chillers

Send cool water to equipment right from your bench top without compromising precision. These chillers maintain constant, uniform temperatures within 0.2° F where other chillers only keep liquid cool within a few full degrees. This makes them ideal for equipment where small temperature changes could cause an issue, such as microscope cooling plates.
Fill these chillers with water or glycol solutions, and an internal pump moves the liquid through a cooling system and out to your equipment. Use the built-in keypad to manually set the temperature, or connect an external controller of your own to automate temperature changes. View the set temperature, alerts, and other information from the LED display.
Chillers rated for 500 Btu/hr. are also known as Peltier chillers. They cool liquid using electricity—no need for compressors or refrigerants. Because they don’t use a compressor, you’ll hardly hear them when they’re on. To check fluid levels at a glance, their tank inlet is semi-clear.

Rack-Mount Liquid Chillers

Save floor space—these chillers mount to standard 19" electronics racks, enclosures, and cabinets. Because they're so compact, you can even fit multiple chillers on the same rack. Where other chillers only keep liquid cool within a few full degrees, these chillers are highly precise, maintaining constant, uniform temperatures within 0.18° F. This makes them ideal for equipment where small temperature changes could cause an issue for your process. Also called Peltier chillers, they cool using only electricity, so there's no compressors or refrigerants. Without a compressor, you'll hardly hear them when they're running.
Fill these chillers with water or glycol solutions, and an internal pump moves the liquid through a cooling system and out to your equipment. There are multiple ways to control these chillers. Use the built-in keypad to manually set the temperature, or connect an external controller of your own to automate temperature changes. View the set temperature, pressure, and flow rate from the digital display. It will also display maintenance reminders and alarms.
A port on the front lets you quickly check fluid levels and fill the chiller with fluid without removing it from the rack or disconnecting it from your system.
