Product Specifications

FEATURES:

The TQ is a complete, all-in-one unit, consisting of pump, motor, pressure tank, and electronic controller. The built-in electronic controller provides constant pressure which ensures that the pump starts automatically when water is consumed and operates continuously until water is not required.
Compact design and quiet operation make the TQ series suitable for many applications.
The TQ is constructed from top quality corrosion resistant materials.
The TQ has an automatic reset function.
The motor has a built-in thermal overload to protect against high operating temperatures and over current. (Single phase motor only)
The TQ has an anti-cycling feature which prevents the pump from continuous starting and stopping when you have a dripping tap or minor leak in the system.
The TQ has a self-priming function which is able to pump water from depths of 25 feet or less. However, on installations with suction lifts over 3 feet, a good quality foot valve should be fitted.

APPLICATIONS:

The TQ series pumps are designed for water supply pressure boosting in residential, commercial and light industrial applications where low or inadequate water pressure exists. It is suitable for boosting pressure from underground or surface water supplies.

SUITABLE LIQUIDS:

Potable water or other clean, thin and non-aggressive liquids.

OPERATING CONDITIONS:

Indoor use only
Ambient temperature: Max. +104°F
Liquid temperature: +39°F ~ +104°F
System pressure: Max. 120 PSI
Relative humidity: Max. 85% (RH)
The incoming water pressure must be lower than the factory start pressure setting for these pumps to function correctly. If your incoming water pressure is higher than the factory start pressure setting then choose a larger pump that has a factory start pressure setting higher than your incoming water pressure.
The internal flow switch will turn the pump on when it detects water flow of 0.75 GPM or greater

Frequently Asked Questions

Q. "How are the TQ pumps activated?"
A. The TQ pumps have a built-in pressure switch and internal flow switch. Either one of these will activate the pump depending on water consumption. The pump will start when the pressure is BELOW the pressure switch activation point, or the water flow rate is greater than 0.7 GPM. The preset pressure switch activation point for each model is provided in the pump specifications chart listed under "start pressure setting (PSI)." The incoming water pressure must be lower than the preset activation point; otherwise the pump will not start.

Q. "One of the features says the TQ has a self-priming function. Does this mean I never need to worry about priming this pump?"
A. When first installed the pump must be primed before operation. The TQ pumps have a built-in check valve, that will allow the pump to then pump water from depths of 25 feet or less without the worry of priming the pump each time. However, the pump must always be checked for prime if not used for a prolonged period of time. It is imperative to fill the pump with water before operation as dry running causes irreparable damage to the mechanical seal.

Q. "Can the 'start pressure setting' be adjusted?"
A. No, these pumps are supplied with a factory preset pressure switch and are not designed to be field adjusted.

Q. "What is the purpose of the built-in pressure tank?"
A. It is designed to minimize motor startup due to small flow demand or a minor leak in your water system. The pressure tank comes from the factory pressurized at the "start pressure setting".
