Armstrong pump traps offer the following features, advantages and benefits:
Non-electric
Utilizes inexpensive steam, air or gas for operation and has no seals, motors, impellers or electric components, which frequently fail.
Wear and corrosion resistance
Mechanism frame assembly is constructed of rugged investment-cast stainless steel components.
Stress chloride corrosion resistance
Inconel X-750 springs have higher resistance to the stress that causes lower-grade stainless steel springs to fail.
Corrosion resistance
Entire float mechanism is stainless steel. Float is Heliarc welded to avoid the introduction of dissimilar metals, which could lead to galvanic corrosion and float failure.
Externally replaceable valve and seat assembly
Maintenance is a "snap" with hardened stainless steel valves that can be cleaned or replaced without cap removal .
Explosion proof
Intrinsically safe due to all-stainless steel construction of mechanism.
Long life and dependable service
Simple float/spring operation and rugged all-stainless steel construction allow for long, trouble-free service life.
Compact, low-profile design
Low-profile design allows for maximum pump capacity with minimal fill head and floor space requirements. PT-300 Series horizontal tank design provides the highest capacity with the lowest profile on the market.
