ARVADA -- Sundyne, a global leader in the design and manufacture of pumps and compressors, today announced the general 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 to 500 gpm (114m3/hr)
• Heads to 5,200 ft (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 Dustin Moran, Sundyne Industrial Business Unit leader.    

In engineering the new P-3400, Sundyne said it increased the horsepower from the maximum 250 HP of the reliable P-3000 to 400 horsepower.

The new 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-percent increase in torque.

These enhancements deliver a 30-percent increase in maximum head, the company said.

Like all Sunflo pumps, Sundyne said the P-3400 features a modular shaft assembly, simplifying repair and minimizing maintenance downtime.

Robust pressure lubricated journal bearings support the rotating elements and provide the Sunflo pump with the ability to withstand system upsets that lead to failure of competitive technologies.

The impellers on the P-3400 feature Sundyne’s unique suction inducer technology for addressing low NPSH requirements and eliminating pump cavitation.

And the single-stage design simplicity of the P-3400 offers a compact footprint that is significantly smaller than competitive pumps, the company said.
