What type of pump is used in the Telma Transmission Retarder?

The Telma Transmission Retarder utilizes a Waterous 1500 GPM two-stage pump. This type of pump is specifically designed to enhance braking performance by using hydraulic principles to slow down a vehicle without relying solely on traditional friction brakes.

The two-stage design allows for better efficiency and adaptability across different operational conditions, providing a consistent level of braking power when needed. The 1500 gallons per minute capacity indicates a robust pumping capability, which is crucial for the effective operation of the retarder system. In situations where managing heat and wear on the brake components is essential, this pump type optimizes performance and prolongs the lifespan of the vehicle’s braking system.

Understanding the specifications of the pump is vital for fire department operations as it directly impacts the efficiency and safety of handling heavy firefighting apparatus during emergency responses. The capacity and design choices are fundamental in enabling better control during various scenarios, which underlines why this particular option is the correct answer.
