Flextool Drive Units & Pumps

Drive units

If you’re using a flexshaft submersible pump, a crucial component is the drive unit. An effective drive unit prioritizes durability and efficiency in its design. Encased within a robust powder-coated tubular steel roll frame, these drive units provide both protection and enhanced portability. The finest drive units also feature integrated lifting hooks, facilitating convenient and secure onsite handling.

What is a drive unit?

Drive units produce rotational motion essential for powering flexshaft concrete vibrators and submersible pumps across various industries like construction, mining, civil engineering, and agriculture. These resilient pieces of machinery come in petrol and diesel variants, offering power options spanning from 4.8 to 9 hp. Users can opt for one of two primary frame designs: the standard 'box' frame, typically employed in stationary applications alongside a flexshaft submersible pump, or the 'dished' design, enabling easy dragging over concrete reinforcing mesh when paired with a flexshaft concrete vibrator.

Flexshaft submersible pumps

When you’re on a worksite, a flexshaft submersible pump can really save the day. Built tough, you can depend on them to pump a wide range of fluids. On a construction site, a submersible pump will come in handy during heavy rains and flooding for dewatering excavation pits and trenches. Here are some more things you need to know before purchasing a flexshaft submersible pump.

What to look for in a submersible pump

Flexshaft submersible pumps are offered in three distinct designs and typically come in lengths of either six or nine meters. The most widely preferred option is the general-purpose pump, known for its versatility across various applications and its lightweight construction, facilitating easy onsite handling. General-purpose submersible pumps are suitable for tasks such as excavation pits, construction sites, pier holes, and swimming pools.

For scenarios involving abrasive fluids contaminated with sand, rubble, or construction waste, abrasion-resistant pumps are the suitable choice. Meanwhile, chemical-resistant pumps are designed to handle chemically contaminated fluids, including salty water and industrial waste, offering a higher level of resistance. It's crucial to remove chemical-resistant pumps from the area when not in use and wash them with clean water to prolong their lifespan. Prior to selecting a pump, it's essential to verify whether your specific application is compatible with a chemical-resistant pump.

To ensure optimum performance and durability, opt for pumps equipped with heavy-duty and double-row oil bath bearings, ensuring maximum service life. Additionally, choose a pump with a corrosion-resistant stainless-steel spindle, and ensure the flexshaft includes a support spring to safeguard it when operating over sharp edges, such as excavations, pits, and dams. For deeper operations, consider using an extension shaft, which can extend the length of an existing submersible pump or concrete vibrator.
