DualPac® Packing Technology Increases MTBR for Mineral Sand Plant

Intro

A mineral sand plant had a slurry pump packed with slurry packing. The packing needed to be replaced when the gland follower bottomed out, resulting in excessive leakage at the gland. Packing MTBR is typically two months. The pump was repacked with Chesterton SuperSet™ with SpiralTrac™ Environmental Controller, and three rings of DualPac® 2211 Packing. According to the customer, the parts were “a win for our plant.”

Challenge

A mineral sand plant has a 14 x 12 – 29 rubber-lined slurry pump. The pump was packed with slurry packing. The medium is slurry with 6 – 2% solids. Operating pressure is two bar, and the stuffing box is flushed with four bar flush water. The packing needed to be replaced when the gland follower bottomed out, resulting in excessive leakage at the gland. Packing MTBR is typically two months. The sleeve was changed out every six months.

Mining Industry Seals

Mining equipment must be able to handle extreme pressures.

Solution

Pump was repacked with Chesterton SuperSet™ with SpiralTrac™ Environmental Controller, and three rings of DualPac® 2211 Packing.

DualPac 2211 Packing is made up of braided technology.

Results

The customer set the flush water flow at 50% of the previous rate. The total amount of water saved per year is estimated to be 21,024,000 gallons/year.

The customer has now applied this solution to three pumps. They repack the pumps every 16 weeks or so (2x MTBR than the previous packing).

The customer says, “When we pull it out, it’s all in one piece, not shredded.”  No sleeve wear has occurred yet due to the SpiralTrac solution.

Customer quote: “This was a win for our plant.”
