Slurry Seals – Flowserve Solutions

LC Chemical Slurry Pump

The LC chemical slurry pump is a horizontal, frame mounted, single stage, end suction design with a tangential discharge nozzle. It is engineered to withstand the rigor of applications that are both abrasive and corrosive.

Thick Wall Concentric Casing With Tangential Discharge is radially balanced and is free of cavities and obstructions that cause wear.

Balancing Counter Vanes Hydraulic Sealing limits internal recirculation and reduces seal chamber pressure. Mechanical seals with radial faces optional.

Rigid, One-Piece Bearing Frame is generously sized to handle belt loads and can be removed easily for maintenance. Allows ample access to seal chamber.

Two Angular Contact Outboard Bearings and a single inboard roller bearing mitigate axial and radial thrust.

Multiple impeller types and pump configurations are available to meet application and installation requirements.

Worthington M Slurry Pump

The M hard-metal slurry pump is a horizontal, single-stage, end suction configuration with a tangential discharge nozzle. The pump fitted with a hard metal liquid end is designed to handle high quantities of coarse, abrasive materials in suspension

SLC Series seals

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.

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.

SLC

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.

SLM 6200

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.

SLM 6000

A single cartridge seal with a flexible stator design. Rugged primary seal faces of sintered silicon carbide, and a monoblock rotor configuration. Available with a Quench Containment Device (QCD) as an outboard seal that can be run with a low pressure water closed loop barrier system or as a single seal with the Synthetic Lubrication Device (SLD) that requires no other equipment.

SLM 6100

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.

Allpac Slurry Pusher Seals

This is Flowserve’s Corrosive duty seals. Provides economic seal life – low operating and maintenance costs. A single, dual balanced robust yet simple slurry with low operation and maintenance costs.

The springs are stationery and outside the pumped medium, which makes the High-performance slurry seal for corrosive applications very suitable for slurry applications.

Springs outside the product avoid clogging

Faces are made from silicon carbide

Large clearances between seal and shaft sleeve

Robust construction

Metal-free design optional

Single and dual seal designs available

Cartridge and component designs available

Single and multiple spring designs available

Allpac N

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.
