Professional-grade 5-chamber agricultural sprayer pump with IP65-sealed motor and ¾" Quick Attach female ports. 4.0 GPM at 60 PSI. Hose barb fittings included. Compatible with herbicides, fertilizers, and insecticides. Not for potable water. Made in the USA.
The Remco 5500 Series is the professional-grade workhorse of Remco's agricultural and industrial pump lineup, and the 90-5516-1E1-82B-SB is the mid-range 4.0 GPM configuration with ¾" Quick Attach female ports — the right choice for sprayer systems that need more output than the entry-level 3.2 GPM model but don't require the maximum 5.3 GPM flow rate, all through the fast-connect convenience of industry-standard ¾" Quick Attach hose fittings.
Powered by Remco's signature completely sealed 12V DC motor with IP65 ingress protection, this pump is engineered for the harshest field environments. Viton valves and a Santoprene diaphragm deliver broad chemical compatibility across the most common herbicides, fertilizers, and insecticides in commercial use. The included ½" straight and elbow hose barb fittings snap directly into the ¾" QA ports for immediate plumbing connection.
On-demand pressure switch control means the pump runs when flow is open and shuts off automatically when the nozzle closes — simple, reliable operation for spot sprayers, boom systems, and fluid transfer applications where no bypass return line is needed.
⚠️ Important: This pump is not listed for potable water use and must never be used with gasoline or any petroleum products. For freshwater RV or drinking water applications, see Remco's PowerRV or Rebel pump series.
Mid-range 5500 Series output with QA convenience — more flow than the 3.2 GPM model for moderate demand applications

Dust-tight and water-jet resistant — rated for harsh field environments and chemical exposure
Viton valves and Santoprene diaphragm stand up to herbicides, fertilizers, insecticides, and more
The Remco 90-5537-1E1-82B-SB is not listed or approved for potable water use. Do not use this pump in any system where the fluid may be consumed by humans or animals. This pump must NEVER be used with gasoline, diesel, or any petroleum-based products. Use only with water-based agricultural chemicals, liquid fertilizers, and other compatible non-flammable fluids. For potable freshwater applications, see Remco's PowerRV or Rebel pump series.
The 90-5537-1E1-82B-SB is engineered for demanding agricultural, industrial, and chemical fluid delivery: Agricultural & Chemical: • Boom and spot sprayers (herbicides, fertilizers, insecticides) • Liquid fertilizer transfer and application • Soft washing and bleaching operations • Agricultural chemical injection and mixing systems Industrial & Municipal: • Dust suppression systems • Equipment washdown • Road maintenance fluid application • General industrial fluid transfer on ½" NPT plumbing systems • Automotive fluid exchange applications
On-demand setup — pump runs when flow is open, stops when closed. 1. Mount the Pump: Secure to a flat surface on your sprayer frame or tank assembly. The pump can be mounted in any orientation. 2. Connect Plumbing: Snap your ¾" Quick Attach hoses directly onto the inlet and outlet ports. Use the included ½" straight hose barb and ½" elbow hose barb fittings to connect ½" hose — these insert into the QA ports without tools for immediate use. 3. Electrical Connection: Connect the 14 AWG leads to your 12V DC supply via relay. A relay is strongly recommended — do not switch the full 16A pump load through a small toggle switch. Protect the supply line with a 20 Amp fuse as close to the battery as possible. 4. Prime & Test: Fill the inlet line before starting to assist with initial prime. Run briefly to purge air, then test at operating pressure. Check all fittings for leaks. Note: A 40A relay is recommended for most installations. Contact Remco at 1-800-228-2481 for wiring guidance.
