Description
The Bertolini PPS 550 VF DURAMAX is a high-performance semi-hydraulic diaphragm pump engineered for demanding chemical applications such as soft washing, spraying, and industrial systems. Delivering 580 psi and 14.3 gpm, it combines exceptional pressure and flow with superior chemical resistance thanks to its DURAMAX polymer construction.
Key Features & Benefits
- Duramax Polymer Technology: Offers outstanding mechanical strength, wear resistance, flexibility across a wide temperature range, and long-lasting durability.
- Chemical Resistance:
- Resistant to freshwater and saline water up to 60°C
- Excellent stability with oils, greases, and glycol-based fluids
- Compatible with pure aliphatic hydrocarbons and mineral oils
- Resistant to alcohols at normal temperatures
- Limitations: Avoid prolonged exposure to solvents, acids, bases, and overheated water (>60°C).
- Enhanced Performance: Independent pulsation dampers ensure smooth liquid flow and improved spray quality.
- Durability: Oil bath lubrication and water-oil heat exchanger reduce operating temperature for extended pump life.
- Applications: Ideal for chemical spraying, agricultural sprayers, and industrial cleaning systems.
