Corken PT Series PT25 2 1/2 in. NPT Cast Iron Sliding Vane Pump

Description

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 PT25 has 2 1/2 in. NPT connections and is suited for transporting gasoline, diesel, fuel oil, and other petroleum products. The flow rates are perfect for home, farm, and fleet fueling applications.
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
