Specialty Diaphragm Pumps Information
MAX‑PASS® S Series — Solids‑Handling Architecture
The MAX‑PASS® S Series incorporates a high‑flow, obstruction‑resistant internal geometry designed to move suspended solids without clogging or performance degradation. Its flow‑through design reduces shear, minimizes pulsation, and maintains consistent volumetric output across varying viscosities.
Key Technical Characteristics
- Flow‑through solids‑handling chamber for reduced blockage
- Optimized check‑valve geometry for improved particulate passage
- Available in plastic or metal wetted materials
- Suitable for abrasive, slurry, and high‑particulate applications
Available Models
Plastic Pumps
- S038 (3/8") — Compact footprint for low‑flow dosing and transfer
- S050 (1/2") — General‑purpose solids‑handling performance
- S100 (1") — High‑flow configuration for demanding process lines
Metal Pumps
- S050 (1/2") — Enhanced durability for aggressive or high‑pressure environments
- S100 (1") — Industrial‑grade construction for continuous‑duty operation
Legacy Plastic Pumps — Proven Chemical Compatibility
All‑Flo’s legacy plastic pumps provide stable performance in applications requiring corrosion resistance, low weight, and compatibility with a broad range of process chemicals. These models are widely used in chemical dosing, wastewater treatment, and general fluid transfer.
Available Models
Plastic Pumps
