| Description: | The SLC Slurry Seal is built tough to withstand the rigors of mining and mineral processing. It’s so tough you can install… |
SLC Series seals are heavy duty single cartridge seals built for the harshest slurry pump services found in mining, mineral and ore processing, and flue gas desulfurization. The SLC Series is designed with a unique non-clogging cone spring that increases seal reliability and enables flushless operation for low operating costs.
Features:
- Encapsulated cone spring increases reliability by providing consistent spring loading and hydraulic balancing to the seal faces without clogging or wearing.
- Abrasion-resistant and corrosion-resistant metal components and silicon carbide seal faces extend seal life beyond slurry pump components to maximize equipment uptime.
- Clean, open design operates without flush water to help reduce product dilution and save significant water-related operational costs.
- Consistent, correct installation is achieved by the cartridge design from the pump equipment’s wet or dry end with no special tools or seal-related bearing housing adjustments.
- Available outboard lip seal and Plan 62 grease or water quench provide lubrication to the seal faces during dry running pump cycles.
- Six group sizes meet the requirements of most slurry pump equipment giving maximum flexibility with minimum inventory.
Operating Parameters:
- Pressures to 20.7 bar (300 psig)
- Temperatures to 77°C (170°F) without quench; 110°C (230°F) with quench; for higher temperature applications contact your local Flowserve representative
- Slurry concentrations to 60% solids by weight
- Particle hardness to 9 MOH
- Surface speeds to 15 m/s (3000 fpm)
- Shaft sizes from 35 to 220 mm (1.375 to 8.661 inches)

Leaching Acid, Primary Processing, Slurry Transfer, Dewatering & Water Supply
Single balanced conical washer spring cartridge seal, designed to operate without a flush in tough slurries. No flush increases plant efficiency, reduces operating costs and eliminates product contamination. The seal incorporates a unique non-clogging cone spring design that increases seal reliability.

| Description | Dual balanced cartridge multi-spring pusher seal |
- Industries:
Dewatering & Water Supply, Leaching Acid, Slurry Transfer, Primary Processing
Dual balanced cartridge multi-spring pusher seal used in very abrasive applications where corrosive, toxic or volatile liquids are being handled and a single seal is not acceptable. The inner and outer seal faces are interchangeable. Uses a pressurized barrier fluid to prevent process fluid from reaching the atmosphere. The outer seal is shrouded by gland as added safety feature. No bypass or external flush needed. When installed into an open taper bore seal chamber. The seal tolerates pressure reversals. Requires enlarged stuffing box. Based on the SL 6000.

| Description | Slurry Seals |
- Industries:
Primary Processing, Dewatering & Water Supply, Slurry Transfer, Leaching Acid
Primary seal faces are a flexibly mounted stator and monoblock rotor in silicon carbide placed in a tandem arrangement along with a low pressure secondary seal having carbon vs. silicon carbide faces. The secondary seal is engineered to last longer than a QCD when a fluid quench is applied. It can also allow operation of a closed loop fluid system when the secondary seal is fitted with a quench circulating device.

DIN24960
Single, tandem or double balanced wavy spring seal cartridge designed according the metric DIN 24960 form C. Each seal face pair uses two 100% identical faces. When used as a double seal the inboard seal is reverse pressurized and therefore very resistant to clogging. This seal is designed specifically for the so-called ‘form C’ part of the DIN standard, and is therefore available only in four sizes.
