Overview

This document provides detailed technical data and specifications for slurry centrifugal pumps equipped with overgear drives for tractors. It includes performance parameters such as flow rates, head (H), and horsepower (HP) across various pump models and configurations.

Flow Rate Units and Conversion

• Flow rates are presented in liters per minute (l/min), cubic meters per hour (m3/h), and liters per second (l/s).
• Example conversions: 600 l/min = 36 m3/h = 10 l/s; 4000 l/min = 240 m3/h = 66.7 l/s.

Performance Parameters

The document tabulates pump head (H) in meters and power requirements (HP) for different flow rates. Multiple sets of H and HP values correspond to different pump models or impeller sizes, indicating performance variations.

• Head (H) values range approximately from 16 to 131 meters depending on flow rate and pump type.
• Horsepower (HP) requirements range from about 4.4 HP to over 121.5 HP.

Pump Models and Specifications

The pumps are identified by model codes such as TL2-85GA, TL4-K125GA, TL4-K100GA, T2D100, TD80, TL3-80GA, TL3-110GA, TL4-100GA, and TL3-K80GA.

• Inlet and outlet sizes are specified, e.g., 3½" x 3½" for T2D100, 2½" x 2½" for TD80.
• PTO (Power Take-Off) speeds and gear ratios are provided, e.g., 860x3.36, 547x5.40, 940x3.41, indicating the mechanical drive configurations.
• Impeller dimensions and pump casing sizes are indicated by numbers such as 462x6.92, 501x6.38, 547x5.85, which likely refer to diameter and width in millimeters.

Key Technical Highlights

• The pumps are designed for slurry applications, implying handling of abrasive and dense fluids.
• Overgear drives allow tractor PTO compatibility, facilitating mobile and agricultural use.
• Multiple impeller and casing sizes enable customization for specific flow and head requirements.
• Performance curves show that as flow rate increases, head generally decreases, while horsepower increases.

Recommendations and Usage Notes

• Select pump model and impeller size based on required flow rate and head to optimize efficiency and power consumption.
• Ensure PTO speed and gear ratio compatibility with tractor specifications.
• Consider slurry characteristics when choosing pump materials and maintenance schedules.

Summary

This technical data sheet is essential for engineers and operators selecting slurry centrifugal pumps for tractor-driven applications. It provides comprehensive performance data, mechanical specifications, and operational parameters to guide proper pump selection and application.
