Horsepower (hp) and nominal flow rates are for the conditions specified at 50 psi (3.5 bar) differential pressure. Refer to performance curves for capacities and horsepower at other operating conditions. Reduced liner models are available with flow and hp of about 75% of the standard models. Note: Viscosity for the MLX4 pump model is limited to 100,000 ssu (21,000 cS).
