Simple, fast sizing and installation, including checking outlet or pipe size for a proper fit.
Range curves and selection charts generated from actual R&D tests for comparing similar well pumps.
Kits configured to run within a 30 Hz minimum and 80 Hz maximum operating frequency range.
Wiring is as easy as standard three-wire control box: (1) L1, L2 and Ground in from power supply (2)Red,
Yellow, Black and Ground out to motor; setup help is also available on YouTube.
Pressure is factory preset at 50 psi with simple, fast, field adjustability for higher pressures, helping
reduce pressure fluctuation pain points that can add system strain.
Three phase output to motor reduces wire cost.
Goulds model GS features the Guardian bearing system to protect components inside the pump from sand and
abrasives and help extend service life.
New – a Switch Input for connecting a pressure switch or float switch.
New – Grounding provisions for transducer and transducer cable.
Goulds Balanced Flow Constant Pressure System model 10GP2020 is a submersible well pump system ProPak kit with
a 2 HP, 230V three-phase CentriPro motor, Aquavar SOLO controller with transducer, and Goulds GS water.
Designed for residential and agricultural water wells, it helps customers find the right fit for well depth,
pressure needs, and pressure tanks across a wide range of well pump applications and other submersible pump setups.
This system is rated for 10 GPM at 60 PSI and well depths up to 380 ft.
It is designed to provide consistent water pressure and
reliable pressure for agricultural uses and irrigation, helping support clean water delivery where steady
performance matters. Its design enables operation with a smaller inline pressure tank, and it features a
wall-mounted NEMA 3 controller that can be mounted outside.
Balanced Flow Controller – NEW FEATURES for Higher Pressures:
New, more versatile user interface board that combines key components in one system to simplify installation
Provides switch connection for an optional pressure or level switch as a useful step when you plan the setup,
and you can hear setup guidance through support resources if needed
New current limit settings for all new CentriPro motors
Built-in protections include dry-well sensitivity for more reliable operation
Built-in protections also include broken pipe detection for easier troubleshooting
These safeguards help support reliable working operation and make troubleshooting easier, with customer
feedback helping improve support when customers need it.
5 or 20 PSI pressure drop restart switch
Transducer better protected from transient power surges
Transducer – NEW AND IMPROVED for Pressure Tank:
Larger port orifice to prevent clogging
Case to electronics surge protection
All Stainless Steel construction for the submersible pump/transducer assembly, built for long-term durability and
resistance to leaks around the assembly
Pressure surge capability without the use of a pressure snubber
Case coupled noise immunity
Reverse voltage protection
Line to electronics ground surge protection on all lines
Transducer cable has ground wire built-in to help you learn what the upgraded transducer content means in
practical use: simpler grounding and more reliable signal performance
Ground clamp provided for transducer to cable grounding
The package includes a 2 HP CentriPro three-phase motor, an Aquavar SOLO controller with transducer, and a Goulds 10GS20 GS water end.
What is the system rating?
It is rated at 10 GPM at 60 PSI.
What well depth is this system designed for?
The supplied product data lists it for wells up to 380 feet.
Does this system need a large pressure tank?
No, the product data states that only a small inline pressure tank is needed.
Can the controller be mounted outdoors?
Yes, the wall-mounted controller is described as NEMA 3 rated and can be mounted outside.
How is the pressure set?
The pressure is factory preset at 50 PSI and can be field adjusted for higher pressures.
What wiring information is provided?
The product data states wiring is similar to a standard three-wire control box, with L1, L2, and Ground in from the power supply and Red, Yellow, Black, and Ground out to the motor.
What motor does this system use?
It uses a 2 HP CentriPro three-phase motor rated at 230 V.
This constant pressure system includes a motor, controller with transducer, and water end, and installation should follow the supplied system wiring and setup information.
Review the included system components and confirm the correct model before installation.
