Tiger Grinder & Multistage Centrifugal Pumps for Industrial and Mining Applications

Grinder and multistage centrifugal pumps are workhorses in mining dewatering, industrial wastewater transfer, and municipal lift station applications. Tiger Pumps — available through Water Services Inc — cover both categories with configurations suited to demanding, continuous-duty environments.

Grinder Pumps: Operational Overview

Tiger grinder pumps (WS-GD and WS-GDH series) are submersible units designed to macerate solids-laden wastewater before pumping, eliminating the risk of blockages in discharge lines. Key specifications across the range:

·       Flow rate: Up to 2,532 GPH

·       Max head: Up to 82 ft (WS-GDH-20-3-60 and WS-GD-20-3-60 series)

·       Power range: 1 HP to 3 HP

·       Voltage options: 220V single-phase / 460V three-phase

·       Discharge connection: 1-1/4 in NPT

·       Frequency: 60 Hz

The three-phase 460V variants (WS-GD-15-3-60, WS-GD-20-3-60, WS-GDH-20-3-60, WS-GD-30-3-60) are the standard choice for industrial facilities and mining sites where three-phase power is available and continuous-duty cycles are required. The single-phase 220V option (WS-GD-15-1-60) suits remote installations or smaller commercial sites.

Pedestal, Rail & Disconnect Systems (WS-TOS-L3, WS-TOS-L4, GD-0247, GD-0257) are available as matched accessories, enabling guided rail wet-well installation and tool-free pump removal for maintenance — critical in confined-space lift station environments.

Multistage Centrifugal Pumps: Operational Overview

The Tiger CDLF series (e.g., CDLF8-8) is a vertical, multistage centrifugal configuration built in 304 stainless steel. These units are suited to:

·       Booster service in water treatment and process water systems

·       High-pressure transfer in mining and industrial process lines

·       RO feed pressure in water treatment skids

Stainless construction resists corrosion in potable water, process water, and mildly aggressive chemical environments. Impeller replacement kits (IRK) are stocked, supporting in-field serviceability without full pump replacement.

Selection Criteria for Engineers and Contractors

For mining dewatering with solids content, specify the WS-GD or WS-GDH series. For process water pressurization or RO feed, specify the CDLF series.
