Self-Priming Pumps for Construction Site Dewatering: A Contractor’s Selection Guide
Reviewed by: Beijing Beibangpu Co., Ltd technical team. Updated: July 2026. A self-priming pump for construction site dewatering is only half the problem facing a contractor. Manufacturers and trade literature already cover the pump itself in exhaustive detail-how it primes,…
Chemical Drum & Barrel Transfer Pumps: Portable Options for Corrosive Liquids
A chemical drum barrel transfer pump is a handheld pump that’s simply lowered into a drum, barrel, or IBC tote and then safely moves your corrosive, flammable, or other hazardous liquid from the container without the need to lift and…
Sewer Lift Station: The Complete Guide to How They Work, Types & Maintenance
![Sewer Lift Station: How It Works, Types & Costs [2026]](https://bbpmfg.com/wp-content/uploads/2026/07/sewer-lift-station-featured-768x512.png)
Reviewed by: Beijing Beibangpu Co., Ltd technical team. Update: July 2026. A sewer lift station is the apparatus that moves wastewater from a low-lying collection area to higher elevation where gravity flow to the wastewater treatment plant (WWTP) is possible.…
Chemical Pumps: How They Work, Material Compatibility, and How to Specify the Right One
Specifying a chemical pump is a different problem from buying any other pump. Wetted material must survive the fluid chemistry, seals must contain whatever leaks past those wetted parts, and the motor has to live in the corrosive vapours surrounding…
Deep Well Pumps: 2026 Guide to Types, Sizing & Lifespan
Deep well pumps lift water from boreholes deeper than 25 feet, where standard surface pumps cannot move water against gravity and atmospheric resistance. This guide covers how submersible, jet, and turbine deep well pumps work, how to size one for…
Booster & Pipeline Pumps: Selection Guide (2026)
Booster & Pipeline Pumps: Selection Guide for Engineers and Buyers Booster & Pipeline Pumps fill the gap between ordinary transfer duty and fully designed pump-station systems. Modern pipeline buyers are no longer just asking for a pump; they are asking…

How Does a Mixed Flow Pump Work? Specific Speed, Impeller Geometry, and Engineering Principles
Quick Specs: Mixed Flow Pump Specific speed (Ns, metric) 35 – 160 Head range (single stage) 5 – 60 m Typical BEP efficiency (large units) 75 – 88% Impeller tip velocity limit 25 – 30 m/s Blade outlet angle…
Axial Flow Pump: A Comprehensive Guide to Theory, Types & Applications
An axial flow pump moves water the way a boat propeller moves a boat: the impeller spins inside a pipe, and fluid travels parallel to the shaft rather than being cast outward as in a centrifugal pump. This geometry change…
