YD-NSF/NSF, YD-LRN series

Overview

High Quality resin construction

The entire pump and its component parts are flawlessly molded with an all resin construction. The Pump’s stability and quality are assured even in the harshest conditions.

All necessary measures taken for thermal expansion

Because the resin is resistant to high temperatures and is constructed to absorb thermal expansion, the pump is capable of handling high temperature solutions and chemicals.

Maintenance Free

Constructed with no consumable parts (such as mechanical seals), the pump is free from problems such as leaks, wear and tear, and excess heat. This makes maintenance and inspection an incredibly easy task with very low maintenance costs.

Valveless

This patented VALVELESS feature have been a World Chemical trademark since 1971. Because of its unique priming mechanism, this pump does not require any foot valves. Also, the built-in check valve increases priming speed and reduces back-flow velocity to retain maximum liquid in the priming chamber at pump shutdown.
