PumpDimᵀᴹ and PumpDim Lite

Features

For settling slurries and manual calculations, Cave’s correlation is the most common method of allowing for the effects of solids on pump performance.
Later methods like the Metso method which include pump size effect are utilized when sizing softwares like PumpDimᵀᴹ are used. These methods are more accurate and the Cave method is often too conservative.

PumpDim Lite was recently launched as a web based subsidiary to Metso PumpDimᵀᴹ.  PumpDim Lite is an advance selection application tool that can facilitate quick budgetary pump proposals and is compatiable on all internet accessible mobile  devices. PumpDim Lite only provides quick pump suggestions/proposals. For exact and applicable pump selections, the Metso PumpDim software should be used.

To obtain a better understanding of the pump sizing process, the inexperienced user is strongly recommended to study the booklet "Slurry Pump Basic" published by Metso Sweden AB. See downloads below.

Pump performance with settling slurries

The results from PumpDimᵀᴹ are representative for settling slurries with “normal” particle size and distribution, such as those found in mineral processing industries, with concentrations lower than 40% by volume.

The program considers and/or calculates for example the following parameters:

  • Critical flow velocity to avoid settling of particles in pipes.
  • The complete pipe head loss system curve when static head, pipes, fittings and other components are specified.
  • Pumping of froth when a froth factor is specified.
  • Effect of solids on the generated pump head and pump efficiency.
  • Recommends material for the pump wet end considering particle size and distribution.
  • Selects pump size for the specified duty and calculates required pump speed.
  • Calculates shaft deflection and bearing life at the duty point.
  • Recommends motor size and drive for the duty.
  • Calculates slurry density based on particle and liquid density and concentration and/or tonnage. Calculates actual flow through an existing installation based on pipe system, slurry properties and pump speed i.e. determining circulating load in mill discharge applications.

Homogenous slurries with particles essentially smaller than 50 um i.e. clays, cement slurries, coating and filler quality calcium carbonates that have a non-Newtonian behaviour, need to be treated as a viscous liquid. The true slurry plastic dynamic viscosity, yield stress and flow index need to be known. These parameters can be established from test work carried out by Metso, or other laboratory.
For particles with a flaky or fibrous shape i.e. some mill scale applications and paper pulp applications need special considerations. Please consult Metso's application specialists.

How PumpDim Lite works

After complete registration, Metso experts will provide a login with username and password to a secure site. From there you can provide any of the following information for a pump proposal:

  • TDH
  • Flow
  • S.G slurry
  • Slurry classificaiton and related limitations according to ANSI Slurry Pump standard
  • Pump type
  • Wet end wear material

PumpDim Lite provides general information about  the selection, the pump and the duty and stores all past and present selections.
