Professional-grade 12V diaphragm pump for SoftWash, soft washing, and sprayer applications. Flo-IQ technology eliminates switch cycling for smooth, variable flow up to 5.3 GPM at 100 PSI. Viton gaskets for bleach and chemical compatibility. Sealed motor, 3/4" quick-attach ports.
The Remco 90-5917-9I1-63B-SB is Remco's SmoothFlo 5900 — a professional-grade 12V DC electric diaphragm pump built specifically for SoftWash, soft washing, and chemical sprayer applications. It's Remco's highest-performing 12V sprayer pump, engineered for professional cleaning contractors who need a reliable, chemical-resistant pump capable of sustained duty cycles under demanding conditions.
The defining feature is Remco's proprietary Flo-IQ technology — a pressure-sensing system that eliminates the rapid switch cycling that wears out standard diaphragm pumps. Instead of switching on and off repeatedly at a fixed pressure threshold, Flo-IQ automatically regulates flow to maintain smooth, consistent output across varying pressures and demands, up to 5.3 GPM at 100 PSI. Viton gaskets make it compatible with bleach and most common cleaning chemicals used in the SoftWash industry. The sealed motor and heavy-duty 14 AWG wire leads protect against moisture and harsh environments, and the pump is made entirely in the USA with professional-grade components.

Standard diaphragm pumps switch on and off rapidly at a fixed pressure setting, which causes switch wear, inconsistent flow, and pulsing output. This cycling is especially damaging in SoftWash applications where the system is frequently running at partial flow. Remco's Flo-IQ technology replaces the fixed-threshold switch with a pressure-sensing system that regulates the pump's output continuously — delivering the exact flow needed at any given moment without cycling. The result is smoother output, less switch wear, and longer pump life in sustained professional use. Flo-IQ also protects against harmful pressure spikes that can occur when flow is suddenly restricted.
