THR4x3C Centrifugal Water Pump for Shrimp Harvesting

Product Brands: Tobee

Tobee® THR Rubber Slurry Pumps are similar to TH metal lined slurry pump in structure. The main difference between TH and THR is the material of wetted parts, which are natural rubber, chloroprene rubber or other wear-resistant rubbers. THR Rubber lined slurry pumps are more suitable in delivering strong corrosive or abrasive slurries of small particle size without sharp edges.

Tobee^® THR Rubber Lined Slurry pumps are interchangeable with world's standard Warman AHR rubber lined slurry pumps for heavy duties,The THR rubber slurry pump is cantilevered, horizontal, centrifugal, natural rubber lined slurry pump for handling strong corrosive or abrasive slurries of small particle size without sharp edges in the mining, mineral dressing, metallurgy, coal, power, building material and other industrial departments etc.

Design Features:

√ 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 designed to 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.

√ Cartridge-style bearing assembly allows for maintenance in a clean environment without removal of the slurry pump, resulting in reliable operation and prolonged bearing life.

√ Grease or oil lubrication bearing assembly options offer ease of maintenance and reduced downtime.

√ Optional dry running shaft seal reduces or eliminates flush water requirements.

√ Effective expeller prolongs packing life while reducing or eliminating flush water requirement.

√ Interchangeability of seal arrangements – full flush, low flow, centrifugal, or mechanical seals may be fitted to any sized slurry pump.

Tobee^®THR Slurry Pumps Shaft Seal Arrangement:

• Packing Seal is a general shaft seal.It applys to various pumping conditions, PTFE and Graphite materials of Packing can be used in high corrosive slurries or high temperature conditions.Using ceramic shaft sleeve,For high abrasion conditions, The ceramic shaft sleeve is available.

• Expeller Seal is an impeller force of reversed centrifugal force, preventing slurry leakage. Expeller seal can be used on the single-stage pump when the positive pressure of pump inlet is no more than 10% of pump outlet pressure or on the first-stage pump in the pump series.

• Mechanical Seal is advanced sealing technique without sealing leakage, The advantages are integrating construction, convenient installation & replacement, The design of mechanical seal and seal box is suitable for liquid flow condition,So it has high abrasion and vibration resistance, Mechanical seal can be used in various severe conditions.
