I work in the industrial pump sector and write about pump selection, system performance, and maintenance. Here at BBP, I share practical explanations of pump components, operating conditions, and common wear issues to help readers understand their options and ask the right questions when choosing or maintaining a pump.
Dry Running in Pumps: What Fails and How to Prevent It
Dry running occurs when a liquid-bearing pump operates without the liquid it needs to cool or lubricate its wetted components. This can lead to damage to the pump. Stop a liquid-dependent pump when dry running is suspected; correct the supply…
Dredging Explained: From Sediment Removal to Final Placement
Dredging is the process of excavating or relocating material underwater. A dredge generally loosens, scoops or suctions sediment and debris from the bottom of a waterway. Projects using that work restore the depth of channels or construct marine infrastructure, or…
Water Pressure in House Is Low: Find the Cause Before Adding a Booster Pump
Low water pressure in a house prompts checking all affected faucets and measuring pressure at a known test point. Check the aerator, valves and filters. Supply problems, such as a break in a supply line or a closed valve, can…
Water Pressure: How to Measure Static and Running Readings
To check water pressure, connect a suitable gauge to a known cold-water test point and take a reading with all water use stopped. Then, take a reading as a named fixture runs water. Compare the conditions, not just the readings:…
How a Siphon (Syphon) Works: Atmospheric Pressure Limits, Plumbing Usage, and Pump Discharge Piping Examples
Reviewed by the BBP Manufacturing Co., Ltd. technical team How Does a Siphon Work? Atmospheric Pressure, Gravity, and Crest Vapor Limits A siphon (also spelled syphon) is a bent tube or closed conduit that transfers liquid from one container over…
Pump Impeller Balancing: Static vs Dynamic Balance, ISO Grades, and Vibration Risk
Key Engineering Takeaways for Impeller Balancing: Single-plane static impeller balancing works for narrow disk-like impellers with diameter-to-width ratio D/b ≥ 6 (or L/D < 0.5) up to 1,000 RPM when machining controls couple unbalance. Two-plane dynamic balancing is recommended above…
API Plan 32 for Pump Seals: Selection, Pressure and Flush Cost
API Plan 32 transfers liquid from an external source into the seal chamber. The supply can protect a mechanical seal when the pumped media can’t provide a proper environment. It also provides liquid to the process. That second consequence typically…
Pump discharge pressure calculation from head and suction
Pump discharge pressure calculation is an energy balance between pump inlet and outlet. Converting the pump head provides the pressure rise, which is then combined with the suction pressure. This analysis focuses on steady liquid flow through industrial centrifugal pumps…
Cartridge Seal Replacement: Check Fit, Duty, and Delivery
A cartridge seal is a preassembled mechanical seal, offered with a sleeve, gland, and associated mounting components. This reduces field assembly and setting work. Replacement requires identification of the correct pump dimensions, face materials, service conditions, and support connections. An…
Pump Seal Leakage: Causes, Checks and Repair Decisions
Liquid escaping through or around the installed sealing arrangement is pump seal leakage. Identify the fluid and find its first wet point and note the time it’s observed. Observations of this nature don’t define if continued operation is safe. Updated…
