Overview
Pulsa Series® 680 hydraulic diaphragm metering pumps are engineered for precise chemical dosing and long-term dependability, delivering superior value. This chemical pump offers a diverse range of fluid handling solutions with unique wet end designs consisting of HYDRAtube®, or flat diaphragm types, each available in a variety of wet-end materials. It complies with the API 675 standard for use in oil & gas, petrochemical, chemical processing, power generation, and water & wastewater treatment industries.
- Hydraulically balanced diaphragm for long life and reduced service costs
- Proven hydraulic management system assures consistent performance and rapid recovery from system upsets
- Material options for safety, durability and chemical compatibility
- Epoxy coating resists corrosion from atmospheric contaminants
- Easy maintenance KOPKit® (Keep on Pumping Kit) saves time and money
- Externally adjustable bypass valve protects the pump from system over-pressurization to quickly adapt to unexpected changes to process conditions
- Internal hydraulic bypass valve for chemical pump protection against system upset
- Full motion stroke length yields 0-100% flow adjustment
- Linear flow predictability over a 10:1 turndown
- 1% dosing accuracy
- Pulsafeeder stands by their equipment with a 5 year gear train warranty
