ROTRON® Seal-Less Water Circulation Pump Features Quiet Running Wet-Rotor Design

High-Performance Pump Delivers Reliable Maintenance-Free Operation for Heavy-Duty Vehicle and Transit Applications

KENT, OH – The ROTRON® SLP 2418 Seal-Less Water Circulation Pump from AMETEK Dynamic Fluid Solutions incorporates a brushless DC motor with a 40,000-hour design life and a quiet-running wet-rotor design. The pump is designed for such demanding applications as transit buses; construction and mining vehicles; and heavy-duty agricultural equipment and on- and off-highway vehicles.

The pump’s wet rotor design circulates cooling water around the motor’s rotor to provide thermal management and lubrication of the bearing system. AMETEK’s seal-less design and brushless motor technology have more than 20 years of field-tested performance in transportation and construction vehicles.

The SLP2418 features a rugged, compact design that includes a stainless steel impeller, cast aluminum pump casing, and an efficient, high-performance, maintenance-free brushless DC motor. Its seal-less design offers leak-proof protection and the capability to resist harsh environmental conditions, such as hot-water spray, salt, fog, shock and vibration. The pump is environmentally sealed to IP 67 standards.

The pump’s industry-leading electromagnetically coupled design has no wet seal to wear out or replace. By eliminating brush maintenance and associated motor failures, its motor is virtually maintenance free. In addition, the pump offers other performance features, including CAN interface, protection from over temperature, current overload, locked rotor, reversed polarity and transient voltage spikes. It weighs only 6.7 pounds and can handle operating fluids from -40o to 95oC.
