Overview

This document provides technical specifications and performance data for the MID series pumps designed for hydraulic motors. The pumps include models MID 40, MID 50, MID 70, MID 70 Inox, and MID MASTER 2”.

Performance Specifications

• Flow Capacity (Q): Expressed in US gallons per minute (Gal. USA/min) and liters per minute (l/min).
• Head (H): Given in meters (m) and feet (ft), representing the pump head or pressure.
• Operating Speed: All models operate at 1400 rpm.

Material and Weight

• Materials: Bronze/Bronzo for MID 40, MID 50, and MID 70; Stainless Steel (Inox AISI 316) for MID 70 Inox and MID MASTER 2”.
• Weights: MID 40 - 7.2 kg; MID 50 - 11.4 kg; MID 70 - 25.5 kg; MID 70 Inox - 11.3 kg; MID MASTER 2” - 21.4 kg.

Performance Curves and Data

The document includes performance curves showing the relationship between flow rate (Q) and head (H) for each pump model. For example, MID 70 shows a head decreasing from 500 m to 165 m as flow increases from 0 to 30 l/min.

Dimensions and Mechanical Details

• Detailed dimensional data are provided for each pump model, including measurements labeled A through P in millimeters.
• Dimensions include inlet and outlet sizes, shaft diameters, and mounting details.

Inlet and Outlet Connections

• Standard connections are BSP (British Standard Pipe) Gas threads.
• Available sizes include BSP-F 2"1/2, BSP-M 2", BSP-M 1"1/2, and others.
• Other connection types and materials (stainless steel or nylon fittings) are available upon request.

Additional Notes

• Standard outlet ports are BSP Gas; alternative outlet types are referenced on page 20 (not included).
• Pipe fittings availability varies by model; some fittings are not available (n.d.).

Summary of Critical Parameters

Best Practices and Recommendations

• Selection of pump model should consider required flow and head to ensure optimal performance.
• Material choice (bronze vs stainless steel) depends on application environment and fluid compatibility.
• Standard BSP connections facilitate integration but alternative fittings are available for specific needs.
