Water Pumps | TT’s Liberator and Trencher comparative guide

TT PumpsTT Pumps provides a comparative guide to its Liberator and Trencher submersible dewatering/drainage pumps.

The Liberator and Trencher submersible dewatering/drainage pumps are two clear favorites within the hire industry and are both perfectly suited for a range of applications. On the face of it, both pumps look somewhat similar in their features, and this poses the question what are the benefits of each? And how do you know which would be most suitable for your application? Here is a comparison of both models to tell you which is more suitable for your application.

The Liberator
The Liberator Range of submersible dewatering/drainage pumps are compact, light and powerful. They are suitable for ground water and water containing sand and silt.

What are the features of the Liberator?

  • Three models available – 400, 750 and 1500.
  • The Liberator is available in 400v, 230v and 100v
  • Resin vortex impeller
  • It is a compact, lightweight and stainless-steel outer casing
  • Urethane impeller
  • Auto reset thermal protector
  • Double mechanical seal
  • 7mm solids handling
  • 4-1.5kW output
  • 50 and 80mm discharge available
  • Interchangeable major components between Trencher, Liberator and Puddle pal
  • Also available in fully 316 stainless steel.

What are the benefits of the Liberator?
Firstly, a clear benefit for the Liberator pump is the interchangeable major components. This means that this pump can be converted from a sub pump to a puddle pump, pumping down to 1mm, giving you two pumps for the price of one. Secondly, the stainless steel outer casing is both hardwearing and extremely easy to clean. The Liberator also features a top outlet to reduce its total surface area for smaller sumps and situations.

TT PumpsThe Trencher
The Trencher range of submersible dewatering/drainage pumps with built in agitator are compact, light and powerful. Like the Liberator, this pump is also suitable for groundwater and water containing sand and silt.

What are the features of the Trencher?

  • Three models available – 400, 750 and 1500.
  • Cast iron casing
  • High abrasive resistance resin vortex impeller
  • Double mechanical seal
  • Integrated agitator
  • Auto-thermal protector – non air locking
  • 4-1.5kW output
  • 50mm and 80mm discharge available
  • Interchangeable major components between Trencher, Liberator, and PuddlePal.
  • Cast iron volute

What makes this pump unique?
This pump features a built-in agitator at the base of the pump, helping to stir where the water is muddy and contains solids – perfect for building sites. The Trencher operates in the conventional method, with the flow going around the inside of the volute area, this is a preference to some.

Conclusion
There are clear benefits to both of these ground water pumps. The Liberator is made from stainless steel outer casing and therefore is easy to clean. With this pump, you have the opportunity to buy a conversion kit where you can convert to a PuddlePal and vice versa – essentially getting two pumps for the price of one. The Trencher on the other hand, features a built-in agitator and an outlet on the side, making it ideal for muddy applications, for example construction sites. This pump is slightly more cost effective than the Liberator, due to the fact it cannot be converted into a puddle pump.
