With a maximum flow rate of 45 GPM and an upper pressure limit of 200 PSI, this Hypro 1700C Roller Pump is your logical choice for low-pressure sprayer application of insecticide, herbicide, liquid fertilizer or your aromatic solvent. This pump features a rotary-action roller principle, which makes your life easier by requiring no check valves during operation. You also gain less friction and a lower starting torque than what's needed for other pumps.
