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 18GP3050 is a submersible well pump system ProPak kit with
a 5 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 18 GPM at 60 PSI and well depths up to 550 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
