Handbook 50 Hz
Handbook 50 Hz
The Grindex Pump Handbook is a comprehensive guide for submersible pumping, offering technical details and solutions for common issues. It includes advanced information like pH tables and friction loss graphs, available for download at www.grindex.com.
The handbook is divided into sections on drainage pumps, sludge pumps, stainless steel (Inox) pumps, slurry pumps, accessories, and technical information, each with detailed specifications and operational guidelines.
These pumps are designed for professional use in challenging environments, capable of handling water with solids and abrasive particles. They ensure continuous, unattended operation in demanding applications.
Details for each pump model include discharge connection size, rated output, maximum power consumption, shaft speed, and rated current. Performance metrics like flow rate and head are illustrated in graphs.
The handbook outlines the construction materials for pump components, emphasizing the use of stainless steel, Hard-Iron™, and other durable materials.
These pumps handle water with high solid content, suitable for tough applications like mining and construction, capable of pumping abrasive particles, mud, sludge, and light slurry.
Inox pumps are designed for corrosive environments, handling pH values from 2 to 10, suitable for saltwater and caustic conditions in shipyards and offshore projects.
Includes sections on calculating friction losses, formulas, friction factors, solids concentration, pH and salt tables, translation charts, and recommended generator sizes for optimizing pump performance.
The handbook is a valuable resource for professionals, providing detailed technical information and guidance for selecting and operating submersible pumps in challenging environments.
- Voltage: Single-phase 230 V, 50 Hz
- Generator and pump models with power, current, cable length, delayed fuse, and generator capacity are specified for models like Mini, Minex Lite, Minex, Minette, Solid, and Salvador.
- Delayed fuses should be dimensioned by multiplying the rated current by 1.75.
- The kVA values are guidelines for selecting the appropriate generator size.
- Consult the generator manufacturer to ensure effective operation.
- Cable sizing should allow a maximum voltage drop of 5% of the nominal voltage.
