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.
