High-Viscosity Pumping: Laminar-Flow References and How to Use Them
Crane 410 assumes turbulent flow. For 1,500-8,000 cP laminar systems use Hooper 2-K, Darby 3-K and ANSI/HI 9.6.7 pump corrections - with a step-by-step method.
Seal Wear Particles in the Product: What Pharma Service Actually Requires
Seal-wear black specks in product are contamination with audit obligations. What works: wear-rate-based replacement, face-material selection and detectability.
Why a Brand New Pump Fails on Day One
Why brand new pumps fail in the first hours: dry start, cavitation, transport damage and misalignment - plus the evidence kit that protects the warranty claim.
Does a Top Tank Inlet Increase Pump Head?
Determine whether moving a tank inlet to the top increases pump head by comparing free discharge, submerged entry, tank pressure and pipe friction.
Pumps for Harsh Chemical Environments: How to Specify One
Choose a pump for corrosive or mixed wastewater by separating controlled chemical-process liquid from grit, rags, sludge and unknown mixtures.
Why Is My Pump Off Curve and Cavitating?
Diagnose a centrifugal pump operating far from BEP without confusing discharge pressure, pump head, low-flow recirculation and true vapor cavitation.
Need Help Applying This Pump Information?
Technical articles are general guidance. Confirm the actual duty point, liquid, materials and installation before selecting a pump.
