Professional-grade 3-chamber bypass sprayer pump with IP65-sealed motor and ¾" Quick Attach female ports. 2.2 GPM at 60 PSI. Compatible with herbicides, fertilizers, and insecticides. Not for potable water. Made in the USA.
The Remco 3300 Series has built a reputation as a solid and reliable industrial performer, capable of continuous heavy-duty workloads. The 90-3313-2E1-82B-SB is the bypass-control configuration with ¾" Quick Attach female ports — built for sprayer systems that keep the pump running continuously, recirculating excess fluid back to the tank when the spray circuit is closed.
Unlike on-demand pumps that cycle on and off with the pressure switch, a bypass pump runs non-stop during operation. When nozzles are open, fluid flows to the boom or spray gun. When they close, the bypass valve recirculates flow back to the tank, keeping the pump at a consistent, steady operating state. This eliminates pressure switch wear and is preferred for systems with frequent or variable nozzle switching.
With ¾" Quick Attach ports and standard Viton/Santoprene materials compatible with the most common agricultural chemicals, the 90-3313-2E1-82B-SB is an ideal choice for ATV and UTV boom sprayers, spot spray systems, and compact agricultural rigs where bypass operation is preferred.
⚠️ 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.

For potable freshwater applications, see Remco's PowerRV or Rebel pump series.
The 90-3313-2E1-82B-SB bypass pump is ideal for compact agricultural and industrial sprayer systems where continuous pump operation is preferred: Agricultural & Chemical: • ATV and UTV boom sprayers with bypass recirculation • Spot spray systems with frequent nozzle switching • Liquid fertilizer application systems • Soft washing and bleaching operations Industrial & Municipal: • Equipment washdown • Dust suppression systems • General industrial fluid delivery on ¾" QA hose systems • Road maintenance fluid application
Bypass setup — pump runs continuously, return line required. 1. Plan the Bypass Return Line: Before mounting, plan your plumbing layout. The bypass port must have an unrestricted return line running back to your supply tank. This line must remain open at all times during operation. 2. Mount the Pump: Secure to your sprayer frame or mounting surface in any orientation, no more than 8 feet above the fluid source for reliable priming. 3. Connect Plumbing: Snap your ¾" Quick Attach hoses directly onto the inlet and outlet ports. Connect the bypass return line to the bypass port. No thread tape or tools needed for QA connections. 4. Electrical Connection: Connect the 14 AWG leads to your 12V DC supply via relay. Protect the supply line with a 10 Amp fuse as close to the power source as possible. 5. Prime & Test: Fill the inlet line before starting. Run briefly to purge air. Verify bypass return flow is reaching the tank and check all connections for leaks.
