Installation / Accessories

The 1300 series is designed for flexibility in installation, starting with a bare pump and adding the appropriate kit:

• Wet-well kit (W): For permanent fixed submerged installations with twin guide bars on a discharge connection. Access for inspection or maintenance is quick and easy by lifting the pump with a chain. The motor is cooled by the surrounding liquid, requiring a minimum liquid level.
• Free-standing kit (H or T): Ideal for portability.
  • Type T (Threaded connection): Portable submerged installation with pump stand and delivery connection.
  • Type H (Hose connection): Portable submerged installation with pump stand and hose connection. The motor is cooled by the surrounding liquid, requiring a minimum liquid level.
• Replacement kit (R): A simple kit to replace an old pump or upgrade to a larger model.

Available accessories include:

• Ball check valve
• Wastewater level regulators
• Command and control panels
• Lifting chains
