Multiflo® LF Diesel-driven Pump Units

Mobile, high-performance and high-head pumps for effective fluid handling where it's needed.

Overview

Multiflo® LF pump units offer robust and high-performing mobile dewatering pump packages for sites with variable conditions. They are especially suited to applications where liquids contain a light to medium percentage of solids or acidic conditions with low pH values.

These diesel-driven pump units consist of high-head pumps that are specifically designed for the effective handling of a wide-range of liquids - from water to sewage and sludge.

Each standard Multiflo® LF pump unit is powered by water-cooled 4 and 6-cylinder diesel engines, and features a non-return valve that allows full flow with minimal restriction.

Compared to other dewatering units, the Multiflo® LF pump unit offers the following benefits:

  • Versatile and highly portable
  • Available with a variety of priming options including an automatic priming system (compressor-fed venturi priming) or a diaphragm priming system to suit the application
  • Features a mechanical seal with glycol quench (biodegradable optional) that allows the pump to start and run dry
  • Features an "environmental box" that separates and silences the air exhaust, and returns liquid to the pump suction
  • Available with skid-mounted options with tie downs, lifting bail, and fork pockets
  • A wide range of suction and discharge fittings and accessories are available

Features and Benefits

Enhanced Abrasion and Corrosion Resistance

The innovative engineering and efficient fluid handling of the Multiflo® LF pump unit are complemented by the heavy-duty wear-resistant materials of construction that include cast steel and cast CD4MCu stainless steel for enhanced abrasion and corrosion resistance.

Casting the pumps from steel creates a more robust pump and additionally promotes extended wear life with the possibility of weld repairing the casing should a problem develop.

Available in Different Configurations to Suit the Application

Multiflo® LF pump units are available in different configurations to meet the varied demands of dewatering applications around the world.

They can be supplied with a portable trailer, or as skid-mounted packages with diesel engines (T3 & T4F rated engine emissions) or electric motors drive options.

No matter the configuration, the Multiflo® LF pump range provides a dependable pumping solution with flow rates ranging from 100m3/h to 3,200m3/h and discharge heads of 10m to 210m.

Reliable Construction

The enclosed impeller is further supported by a stout bearing frame and large-diameter shaft that is less prone to deflection during cavitation.

The Multiflo® LF pump range is more forgiving than similar pumps on the market and the design is proven to result in fewer bearing failures and far fewer instances of shaft breakage in extreme conditions.

Great Efficiency

The pump features a hydraulically superior enclosed impeller design and larger-diameter pump shafts that allow the Multiflo® LF pump unit to efficiently handle large solids while reducing operational and maintenance costs.

This is achieved through the advanced, high-efficiency pump-end that requires less energy to process fluids, operating under reduced power requirements, and in-turn consuming less fuel (LPH) or electricity (kW/h).

In addition to being highly versatile and mobile, the Multiflo® LF pump unit is engineered for efficiency with a proven, enclosed impeller design and leading-edge materials that dramatically reduce total cost of ownership.

Provides a Mobile Dewatering Solution

These units offer a robust and high performing mobile dewatering pump solution. They are suitable for sites with variable conditions, including applications where liquids contain high percentages of solids to be transported or acidic conditions with low pH values.

Applications

Multiflo® LF pump units are frequently used in applications that involve liquids and slurries with a low to medium concentration of solids.

These pump units feature inbuilt skid runners fitted with 25mm (1 inch) wear plates as well as the option of a bolt-on push bar to aid in manoeuvrability around site.

These self-priming pump units offer an effective and low-footprint dewatering solution for a number of industries including mining, sand and aggregates, and general industry. They are frequently used in open pit mining, surface extraction and tailings water reclaim applications as both primary and booster pump units.
