Notes:
Capacity: Capacity figures are based on water using 1725 rpm motor. Capacity will decrease by approximately 1.5% for each 100 psi increase in pressure.
Accuracy: Accuracy is ±1% of full scale over the range of 10% to 100% of capacity.
Temperature / Viscosity: Contact us for temperatures over 200°F (93°C) or viscosity greater than 1000 centipoise.
PVC head pumps are satisfactory for temperatures to 125°F (52°C).
