An Application-First Approach

Industrial mixing directly influences product quality, process reliability, equipment life, and operating costs. Selecting the right mixer takes more than horsepower and impeller size. It requires understanding process objectives, fluid behavior, tank geometry, and long-term operating conditions. Philadelphia combines decades of engineering expertise with advanced design tools, including:

Application engineering
Computational process modeling
Pilot and full-scale testing
Custom mixer design
Mechanical and hydraulic analysis
Field testing and commissioning
Technical service and aftermarket support

Shaft mixers range from 10–600 RPM, while aerators are 300–1800 RPM.

How does the ragless impeller prevent clogging?

Its open, winged design sheds debris naturally during rotation.

Can I install a portable mixer in a lift station?

Yes. FDX-series mixers mount easily and include tethering features.

What’s the lead time for a gearbox exchange?

We stock common gearboxes for next-day exchange in NY & New England.

Are Philadelphia mixers energy-efficient?

Yes. Each system is engineered around your process, and optimized impeller geometries help reduce energy consumption and total cost of ownership.

What power requirements do surface aerators need?

Models range from 0.5 to 15 HP depending on basin size and depth.

Do you offer skid-mounted rapid mix solutions?

Yes. Fully instrumented rapid-mix/fine-mix chemical feed skids are available.

Are there options for corrosive environments?
