Sundyne, a US-based designer and manufacturer of pumps and compressors, announced 8 May the availability of the integrally geared high-pressure Sunflo Industrial Grade P-3400 pump. The 400 horsepower version extends the performance of Sunflo Industrial Grade pumps by expanding the performance envelope with flows up to 500gpm (114m3/hr) and heads to 5,200ft (1,585m).
“The Sunflo P-3400 is our response to customer demand for an industrial grade pump that can address high-pressure in industries where Sunflo pumps are currently used – such as boiler feed, reverse osmosis, well injection, NOx suppression - or high pressure wash down applications that are common across the power generation, maritime, transportation or food and beverage industries,” said the Sundyne Industrial Business Unit leader Dustin Moran.
In engineering the P-3400, Sundyne increased the horsepower from the maximum 250 horsepower of the P-3000 to 400 horsepower. The P-3400 is equipped with a heavy-duty carbon steel frame assembly, a newly-designed impeller that can withstand higher hydraulic loads, a heavier bearing system, and an improved gear set capable of transmitting a 60% increase in torque. These enhancements deliver a 30% increase in maximum head.
The P-3400 features a modular shaft assembly to simplify repair and minimise maintenance downtime. Pressure lubricated journal bearings support the rotating elements and provide the Sunflo pump with the ability to withstand system upsets. The impellers on the P-3400 feature Sundyne’s suction inducer technology for addressing low NPSH requirements and eliminating pump cavitation.
