Silty Trench Dewatering Pump Kit | EVAK Trenchman 400
type: Product
description: Silty trench dewatering pump kit for muddy water, fines and settled silt This FPS Engineered™ kit pairs the EVAK Trenchman 400 with 20m of 50mm layflat hose and a stainless-steel clip. The Trenchman has a built-in agitator, which is what separates it from every other pump in our site range. Part of our wider site drainage and EVAK ranges. Why a pump alone cannot clear silty water A pump can only move what is in suspension. Once silt, sand and fines have settled out, they behave less like water and more like ground. A standard drainage pump sitting on top of that layer will happily draw the clearer water above it and discharge that instead, hour after hour, while the sludge stays exactly where it is. You end up with a trench that looks pumped and is still full of material. The Trenchman has an agitator at the intake: a rotating element that disturbs settled material and lifts it back into the water so the pump can carry it away. Free passage of 15mm then gives that material somewhere to go, where a 5mm pump would simply block. The result is that you remove the silt rather than the water sitting on top of it, which is usually the whole point of dewatering a trench in the first place. At a glance Built-in agitator: Stirs settled silt and fines back into suspension so they can be pumped out. 15mm free passage: Three times the Drainox, so fines, grit and small stones pass rather than block. Around 189 litres per minute: Through the 20m of layflat supplied, at a typical 2m lift. 12 metres of head: Still moving 119 litres per minute at an 8m lift. Automatic float control: Left in the trench, it works while you get on with something else.
