Pump Technology & Maintenance Guides
Explore practical guides on centrifugal pump priming, mechanical seal selection, replacement, and maintenance. These resources help plant and maintenance teams understand common service considerations and identify the operating details to discuss when requesting pump support.
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.
Centrifugal Process Pump or Sludge Pump? A Boundary Checklist
“Sludge” does not describe one consistent liquid. It may be a pumpable liquid with limited suspended solids, or a thick, settling mixture containing fibers, grit, grease and gas. Choosing between an ANSI…
Chemical Pump Material Selection: Data to Confirm First
“Stainless steel pump” is not a complete material specification. A chemical-process pump contains several wetted components, and the environment that controls their performance includes more than the chemical name. Concentration, temperature, impurities,…
System Curve, BEP and Low-Flow Pump Operation
A pump does not impose one fixed flow on every system. The actual operating point is created by the interaction between the pump and the system. Understanding that interaction is essential when…
Mechanical Seal Failure Root Cause Checklist
When a centrifugal-pump mechanical seal leaks repeatedly, replacing the seal may restore operation without correcting the cause. The seal operates at the boundary between a rotating shaft, stationary housing, pumped liquid and…
Repair or Replace an Industrial Process Pump?
A leaking seal, damaged impeller or noisy bearing does not automatically mean that the complete pump should be replaced. It also does not mean that replacing the failed part will solve the…
Urgent ANSI Pump Replacement Parts RFQ Checklist
When a process pump is down, the fastest message is not always the fastest route to a correct quotation. “Need impeller urgently” leaves the supplier to ask for the pump size, part…
Need Help Applying This Pump Information?
Technical articles are general guidance. Confirm the actual duty point, liquid, materials and installation before selecting a pump.
