These pumps, manufactured by USFilter/Wallace & Tiernan (W&T), are renowned for their reliability and versatility in various applications, particularly in the handling of challenging fluids.
What is a Rotho Hose Pump?
A Rotho Hose Pump is a type of positive displacement pump that utilizes a flexible, reinforced hose as its pumping element. This hose, often made of rubber or synthetic materials, is placed within a rigid casing and is compressed by rollers or shoes. As the hose is squeezed, the fluid inside is forced forward, creating a continuous flow.

This document expands on the information provided, breaking it down into chapters for easier understanding.
Chapter 1: Techniques for Utilizing Rotho Hose Pumps
Rotho hose pumps, while relatively straightforward, require proper operation and maintenance techniques for optimal performance and longevity. Key techniques include:
Priming: While self-priming, ensuring the inlet is properly sealed and free of airlocks is crucial for efficient priming. Techniques may include bleeding air from the system manually or using a vacuum pump if necessary.
Fluid Compatibility: Choosing the correct hose material is vital. The hose must be compatible with the fluid being pumped to avoid degradation or contamination. Consult the manufacturer's specifications for compatibility charts.
Flow Rate Adjustment: Rotho pumps often allow for adjustment of flow rate. This involves modifying pump speed or roller pressure (depending on the model). Understanding this adjustment is vital for optimizing the process.
Maintenance: Regular inspection of the hose for wear and tear is essential. This includes checking for cracks, abrasions, or bulges. Replacing the hose at the first sign of significant wear prevents failures and ensures safe operation. Lubrication of moving parts is also crucial to minimize friction and extend pump life.
Troubleshooting: Understanding common issues such as low flow, pulsation, or leakage is crucial for effective troubleshooting. This often involves checking for blockages, hose damage, or faulty seals.

USFilter/Wallace & Tiernan (W&T) offers a variety of Rotho hose pump models, each designed for specific applications and flow requirements. Key model distinctions often include:
Flow Rate: Pumps are available with a wide range of flow rates, from low-flow applications to high-capacity pumping.
Pressure: Maximum discharge pressure varies across models. Selection depends on the system's pressure requirements and the fluid properties.
Hose Material: Different hose materials (e.g., natural rubber, synthetic rubber, polyurethane) offer varying degrees of chemical resistance, abrasion resistance, and temperature tolerance. Choosing the right material is crucial for long-term pump operation.
Drive Mechanism: Some models may utilize electric motors, while others might use pneumatic or hydraulic drives. The choice depends on factors like power availability and the need for precise speed control.
Size and Dimensions: Physical dimensions vary across models, impacting installation space requirements.
Chapter 3: Software and Control Systems for Rotho Hose Pumps
While basic Rotho pumps may not require sophisticated software, advanced models or integrated systems may utilize:
SCADA (Supervisory Control and Data Acquisition) Systems: These allow for remote monitoring and control of the pump, providing real-time data on flow rate, pressure, and other parameters.
