HMD Kontro GSPLF Low Flow API 685 Pump

Low-Flow API 685 Pump – GSPLF

Specifically for Low Flow Duties

The GSPLF combines the proven technologies of Sundyne Barske Wheel hydraulics with the HMD Kontro sealless magnetic drive, optimising reliability and efficiency to ensure trouble-free plant operation. The GSPLF meets the requirements of API 685, making it ideal for heavy duty applications in oil and gas, chemical and petrochemical installations. An additional advantage is the flexibility inherent in the GSPLF diffuser and impeller, which can easily be upgraded should the duty need to be changed, without replacing the pressure casing.

Key Design Features:

• Barske Wheel hydraulics for optimum efficiency at low flows.
• Removable diffuser allows for re-rating of pumps to meet different process conditions without costly machining.
• Suction tuned inducers providing optimum performance for low NPSHa conditions.
Fully compliant to the API 685 sealless centrifugal pump standard.
Total product containment with no leaks or emissions, improving operator safety and environmental protection.
No seals or seal support systems to maintain, reducing overall lifecycle costs.
Easy to install, commission, operate and maintain, with no requirement for special tools.
