The Yamada LLC-2Y Liquid Level Controller is a totally pneumatic system designed to automatically start and stop Yamada Air-Powered Double Diaphragm Pumps when the liquid level within a tank, sump, etc. reaches predetermined levels.
An extremely versatile controller, the LLC-2Y can be used in both single and dual pump applications with any size or model Yamada pump. Used in a single pump configuration, it automatically controls either the filling or emptying of a tank or other vessel. When connected to two separate pumps, it will control both the filling and emptying of the tank.
This dual pump capability is particulary useful for waste water storage, contaminated water clean up, and other applications where liquids are regulary transferred into and out of single vessel.
Dry-run detection
The Yamada DRD-100 detects increases in air volume due to loss of prime or dry-running, and automatically shuts down the pump to prevent excess cycling and increased diaphragm wear.
Extends life of diaphragm
Eliminate air consumption in dry run applications
Prevents air valve from premature failure
Intrinsically safe operation
Supports remote warning systems
Pulsation Dampeners
Yamada Pulsation Dampeners incorporate a flowthrough design which keeps solids in suspension, maintaining dampener effectiveness. A completely automatic air motor self-relieves if reduction of discharge head condition occurs.
