Liquid Level Control – SANDPIPER Genuine Accessories


Overfilling or emptying a tank can result in costly downtime during certain critical processes. When containers are not visible or are inaccessible, a high-low level switch can be used to measure or control the level of liquid inside a fixed area.

The SANDPIPER Liquid Level Control is an automatic, float-actuated control switch capable of opening or closing the air supply to your air-operated double-diaphragm (AODD) pump. Useful in sump, dewatering, fluid transfer or tank filling applications, the liquid level control allows you to regulate an AODD pump by turning the unit on or off as determined by the fluid’s liquid level.

The liquid level control:

  • Is completely groundable, pneumatically operated and requires no electrical connections. This allows the unit to be easily installed into any existing air line plumbing that would power an AODD pump.
  • Is ATEX-certified
  • Can be installed into hazardous areas
  • Is designed for safety and reliability. The float and connection rods that come into contact with fluid are made from stainless steel.

Universal AODD Pump Accessory

The liquid level control can be used in conjunction with any AODD pump. Providing either high or low on/off capability, the liquid level control is completely adjustable to any liquid level within its operating range of a few inches to approximately 9 feet in total.

Other features include:

  • Automatic operation
    • Preset float travel distance and set high or low on/off capacity; the unit will continuously operate without intervention
  • Easy, low-cost installation
    • Control is installed as part of air line plumbing
  • All-pneumatic operation
    • No electrical connections
  • Simple installation and ease of maintenance
    • Easy to install and operate
  • Reliability
    • Stainless steel float and connecting rod offer corrosion-resistant wetted parts
