Teflon Shaft Packing with Lantern Ring for 250 Type Centrifugal Pumps

In demanding oilfield and industrial pumping applications, reliable shaft sealing is critical to pump efficiency, service life, and operational safety. The Teflon Shaft Packing with Lantern Ring is specifically designed for 250 type centrifugal pumps, providing stable sealing performance under abrasive and corrosive working conditions.

Designed for 250 Series Centrifugal Pumps

This Teflon packing is widely used in MISSION / MCM / HALCO / Harrisburg / TSC and other compatible 250 centrifugal pump models, ensuring proper sealing between the pump shaft and stuffing box. It is suitable for pumps handling drilling fluids, slurry, mud, water, and chemical mixtures commonly found in oil & gas and mining operations.

Advantages of Teflon (PTFE) Packing

Compared with conventional packing materials, Teflon (PTFE) offers several key performance benefits:

• Excellent chemical resistance, suitable for corrosive and aggressive fluids

• Low friction coefficient, reducing shaft wear and power loss

• Good thermal stability, maintaining sealing performance over a wide temperature range

• Non-hardening material, helping prevent shaft scoring and premature failure

These properties make Teflon packing an ideal choice for continuous-duty centrifugal pumps where reliability and reduced maintenance are essential.

Lantern Ring for Improved Lubrication & Cooling

The integrated lantern ring allows grease lubrication or flush fluid injection, helping to dissipate heat, flush away solids, and maintain consistent sealing pressure. This design improves packing life and reduces the risk of leakage or overheating during extended operation.

Interchangeable & Easy to Install

The P25PMST packing set is manufactured to match standard OEM dimensions, making it fully interchangeable with original parts used in 250 series pumps. It can be easily installed during routine maintenance or overhaul, minimizing downtime and simplifying inventory management.

Typical Applications

• Oil & gas drilling and cementing operations

• Mud circulation and slurry transfer systems

• Pump rental fleets and repair workshops

• Industrial fluid handling requiring chemical-resistant sealing
