Brand: K-Rain SKU: 14003
Product Overview
The K-Rain 14003 ProSport is a heavy-duty 1-inch gear-driven rotor designed specifically for sports turf and larger commercial landscapes. Its triple-nozzle configuration combines one primary long-range stream with two secondary streams for mid-range and close-in coverage, helping reduce the dry area that can occur near a large rotor while still reaching across broad turf panels.
The standard-speed ProSport adjusts from 40° to continuous 360°, allowing one rotor to serve perimeter and full-circle positions. Current K-Rain specifications list a radius of approximately 43 to 77 feet, a flow range of approximately 5.1 to 32.5 GPM, and a 40- to 90-PSI operating range. The 1-inch female NPT inlet and higher flow demand make this a sports-field and commercial rotor rather than a direct hydraulic substitute for a residential 3/4-inch rotor.
A factory-installed check valve helps control low-head drainage, while the heavy-duty rubber cover and mud guard allow the sprinkler to be set below grade and help protect players and equipment from the exposed head. The arc-memory clutch helps protect the gear drive if the turret is forced. Select the nozzle and spacing from measured dynamic pressure and available flow; large-rotor zones often require dedicated piping and carefully sized valves.

Compatibility and Installation Notes
Verify the lateral pipe, valve, pump, and service line can deliver the selected nozzle's flow at operating pressure. Use K-Rain performance tables for spacing and precipitation calculations. The standard 14003 is the plastic-riser model; select 14003-SS when a stainless-steel riser version is required. Maintain the factory check valve and install the rotor at the correct below-grade elevation for the field surface.
Frequently Asked Questions
Can the 14003 replace a residential 3/4-inch rotor?
Not as a direct hydraulic substitution. It has a 1-inch inlet and substantially higher pressure and flow requirements.
Is a check valve included?
Yes. K-Rain lists a factory-installed check valve for the ProSport.
What is the benefit of the triple nozzle?
It combines long-range, mid-range, and close-in streams for more complete distribution across the radius.
Why Buy the K-Rain 14003 ProSport from Big Frog Supply?
The 14003 provides sports-field coverage in the standard plastic-riser configuration without the added cost of the stainless-steel option. Big Frog Supply also carries the 14003-SS, ProSport nozzles, check-valve parts, and other K-Rain rotors for matching the field design and service requirements.
