Cotton Fiber Packing (Grease Impregnated)

Cotton Fiber Packing (Grease Impregnated)

Core Features

  • Natural Long-Staple Cotton Matrix: Braided from high-grade, long-fiber cotton yarns. Cotton is naturally soft and highly resilient, allowing it to conform perfectly to the contours of the stuffing box and the shaft.
  • High-Pressure Grease Saturation: Every strand is thoroughly impregnated with a specialized, high-viscosity industrial grease. This deep-soak treatment ensures the packing remains “wet” and lubricated throughout its entire cross-section.
  • Superior Water Resistance: The grease acts as a hydrophobic barrier, preventing water from being absorbed into the core of the fiber. This significantly reduces the risk of the packing swelling or rotting in stagnant water environments.
  • Ultra-Gentle on Hardware: Cotton is one of the most non-abrasive materials available. It provides a reliable seal without the risk of scoring or “necking” soft metal shafts like bronze, brass, or untreated stainless steel.
  • Excellent Thermal Conductivity (at low speeds): The grease helps transfer frictional heat away from the shaft interface, ensuring the packing stays cool during standard water-pumping operations.
  • Economical and Reliable: Offers an extremely cost-effective solution for general-purpose utility service where high-tech synthetics are unnecessary.

At Kriloha Ltd., we recognize that some of the most reliable industrial solutions are the simplest. For standard water-moving equipment, you don’t need ballistic fibers; you need a material that is “kind” to your machinery. The Kriloha Grease-Treated Cotton Packing is our engineered answer for “Gentle-Service” universal containment. As a premier global provider of braided seals, Kriloha Gaskets has mastered the Square-Interlock Braid technology required to turn natural vegetable fibers into a high-performance fluid barrier.

The engineering of our Cotton series is based on Matrix Resilience. Unlike stiffer synthetic yarns, cotton “breathes” and adjusts to the mechanical run-out of older equipment. At Kriloha, we utilize a specialized vacuum-impregnation process to force industrial grease deep into the fiber core. This creates a “Lubricant Reservoir” that ensures a cool startup and long-term protection against frictional heat. This grease also acts as a preservative, preventing the natural cotton fibers from breaking down in seawater or damp environments.

Manufacturing this packing at Kriloha involves strict Fiber-Purity Calibration. We ensure our cotton yarns are free from seeds or low-grade fillers that could cause shaft wear. Whether you are sealing a municipal water pump or a marine propeller shaft, Kriloha Grease-Treated Cotton Fiber Packing provides the mechanical simplicity and hardware safety your facility demands. By choosing Kriloha Ltd., you are investing in a “Time-Tested” technology that protects your equipment while remaining budget-friendly.

Primary Use Cases

  • Municipal Water Utility Pumps: The traditional choice for cold water and drinking water systems where a clean, lubricated seal is required.
  • Marine Stern Glands & Rudder Posts: Providing a classic, water-resistant seal for propeller shafts on boats and commercial vessels.
  • Agricultural Irrigation: Ideal for high-volume irrigation pumps where maintenance is performed in the field and cost-efficiency is paramount.
  • Hydraulic Accumulators: Used in low-pressure water-based hydraulic systems and older industrial presses.
  • General Household & Industrial Sump Pumps: Handling clean or slightly silty water at moderate temperatures.

FAQs

Frequently Asked Questions (FAQs)

Why use Grease-Treated Cotton instead of Graphite-Treated?

Grease-treated packing offers superior water-shedding properties. It is better for marine applications or pumps that stay submerged, as the grease prevents the fiber from waterlogging and rotting.

Will this packing score my shaft?

No. Cotton is a soft organic fiber. It is virtually impossible for this packing to score a metal shaft, making it the safest choice for bronze or brass sleeves.

What is the maximum temperature for this packing?

Cotton is designed for moderate temperatures, typically up to +100°C to +120°C (212°F to 248°F). Beyond this, the grease may liquefy and “wash out.”

How much “leak-off” is required?

A steady drip (approx. 10–15 drops per minute) is essential. Organic fibers rely on this flow to dissipate heat and prevent the fiber from charring.

How do I install Grease-Treated Cotton Packing?

Cut the packing into rings with a 45° miter joint. Stagger the joints by 90°. During startup, tighten the gland nuts finger-tight and adjust slowly as the pump reaches operating speed to ensure the grease can establish a lubricating film.
