EP078-1D21 Stuffing Box is used for 6x4EE-AHP Horizontal Slurry Pump.
Slurry pump stuffing box of a sailboat will have a stern tube that is slightly bigger than the prop shaft. It will also have packing nut threads or a gland nut. The packing is inside the gland nut and creates the seal. The shaft is wrapped by the packing and put in the gland nut. Through tightening it onto the stern tube, the packing is compressed, creating a seal against the shaft. Creating a proper plunger alignment is critical for correct flow and a long wear life. Stuffing box components are of D21 cast iron, A05 high chrome, stainless steel, brass or other application-specific materials.
6/4EE-AHP Slurry Pumps fully lined high pressure pump for multi-stage application
Based upon the popular AH series pump, the AHP/AHPP series high pressure pump offers the same features and benefits as the AH pump, including identical hydraulics at up to 1,000 psi. The high pressure capability allows the user to operate several pumps in series all consolidated into one pump house, saving the expense of supporting systems like gland water supply systems in an alternative design of several pump houses along the transport line.
AHP Slurry Pumps Design Features:
• Multi-stage high pressure operation to 1000 psi (6,900 kPa)
• Heavy duty construction with through-bolt design provides ease of maintenance and minimal downtime
• Ductile iron fully lined casing provides durability, strength, safety, and long service life
• Large diameter, slow turning, high efficiency impellers designed to achieve maximum wear life and low operating costs
• Large, open internal passages reduce internal velocities, maximise wear life and lower operating costs
• Thick elastomer or alloy bolt-in liners provide superior corrosion resistance plus offer ease of liner change-out and interchangeability to reduce overall maintenance costs and maximise wear life
• Minimal shaft/impeller overhang reduces shaft deflection and increases packing life
• Grease or oil lubricated bearing options offer ease of maintenance and reduced downtime
• Cartridge-style bearing assembly allows for maintenance in a clean environment without removal of the pump, resulting in reliable operation and prolonged bearing life
•Now featuring WRT throatbush and impeller combination designed to enhance efficiency and improve wear performance
