Corken PT Series PT30 3 in. NPT Cast Iron Sliding Vane Pump

Corken's PT Series is a special type of rotary positive displacement pump, known as a sliding vane pump. Sliding vane pumps have many of the positive displacement advantages of the gear pump, plus the ability to compensate for wear, and operate at a lower noise level. The PT30 has 3 in. NPT connections and is designed for high flow bulk delivery applications such as aviation fuels, gasoline, diesel, ethanol, biodiesel, and many more.

Other configurations available. Please call 1-800-333-3331 for other options such as strainer, nitrile rubber seals or valve settings.

Note: The PT Series is dimensionally interchangeable with Blackmer pumps.

Features

• Installation is simple since the PT-Series pumps are dimensionally interchangeable with the competition
• O-ring design delivers maximum sealing capability and is available with optional seal materials
• Corrosion resistant bypass valve made of nickel plated cast iron
• Available with a standard bypass valve or an optional air operated valve (AOV) for high and low flow control
• Additionally, the AOV relieves the pressure in the lines for easier handling of the hose nozzle
• Reliable mechanical seal design with optional seal materials
• Heavy duty ball bearings provide greater durability and strength
• Hollow rotor helps reduce weight
• Available with a T-style strainer that keeps your pumping system free from damage caused by welding slag and foreign materials left in the piping or tank
• Conveniently located drain plug allows you to empty the pump quickly when necessary
• Positive displacement sliding vane design delivers higher pumping efficiency and a lower noise level
• The self adjusting vanes extend the life of the pump by compensating for wear
• Viton® elastomers ensure compatibility with a wider range of fluids such as biodiesel and ethanol blends
