The Varisco ST-R Self-Priming Trash Pumps are designed for heavy-duty applications that involve pumping liquids with large solids in suspension. These pumps are typically used in sewage systems and purification plants. Here are the key features and benefits:

Features:

1. Self-Priming: These pumps can prime themselves quickly, without the need for a foot valve. Once filled with water, they automatically prime to a height of up to 7.5 meters.
2. Large Solids Handling: Equipped with a two-vane open impeller, the pump can handle solids up to 3 inches (76 mm) in diameter, making them ideal for sewage and sludge applications.
3. Easy Maintenance: The rotating assembly can be pulled out from the back for easy maintenance without requiring the disassembly of pipes or pump casings.
4. Heavy-Duty Construction: The pump casing is made from GJS 400 ductile iron, ensuring durability and resistance to wear.
5. Operator Safety: As the pump is placed above the liquid to be pumped, operator safety is prioritized. This design minimizes health and safety risks during inspection and maintenance tasks.
6. Replaceable Wear Plates: The pump features abrasion-resistant rubber-faced cast iron wear plates that can be easily replaced.

Applications:

• Treatment Plants: Ideal for handling slurry or wastewater with solid particles.
• Sewage Systems: Can be used for efficient pumping of waste with suspended solids.

This self-priming trash pump is a reliable solution for environments requiring high durability and ease of maintenance, especially when dealing with challenging materials.
