Predictika · Slurry pump selection

An AI sales agent's slurry pump selection, checked before it goes out

An AI sales agent prepares a selection for a Warman horizontal slurry pump: the pump family, the application, the discharge size, the flow, head and pressure, the number of pumps in series and the lining. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the published pump family limits and application table and returns a verdict, every reason and the figures it computed.

Scope: Warman horizontal slurry pump selections across 12 pump families (AH, WBH, MCR/MCU, HTP, AHP/AHPP, XU, HH/H/HRM, L, AHF/LF/MF, GSL, WGR and MDC): application, size, flow, head, pressure and lining. See everything this validator covers

This validator models Warman horizontal slurry pump selections, not just the scenarios shown below.

  • Application — each pump family is checked against the brochure's table of typical applications (23 applications such as SAG mill discharge, coarse tailings, oil sands, coal, flotation and FGD). An application that is not in the table is sent to a person, because the brochure asks that special applications go to a Weir Minerals representative.
  • Family limits — the discharge size range, maximum capacity, maximum head and maximum pressure printed for each family, checked against the duty. Pumps in series add their head; the quote's stated capacity is compared with the family's printed capacity.
  • Lining — the XU and MDC wet ends are all-metal and unlined, so elastomer liners are blocked on them.

Any Warman horizontal slurry pump selection that touches these rules is in scope — not only the scenarios pictured here. Not covered: prices (Weir does not publish Warman prices, so this validator produces no price build-up or line-item quote), pump curves and the final hydraulic duty point (the brochure's selection charts are approximate clear-water performance for preliminary selection only), slurry properties such as particle size, concentration and abrasiveness, seals, drives, spares, and other Warman ranges such as vertical, submersible and dredge pumps. Assumptions: the head from pumps in series is taken as the sum of each pump's maximum head, which is an engineering simplification and not a Weir statement; the limits are the family maxima printed in the brochure, not the limits of each individual size.

Where rules-based CPQ gets it wrong
Click to expand
    
Our assessment of what a typical rules-based CPQ (product rules, price rules and validation rules, as in Salesforce CPQ) does with the same cases. It is a judgment about effort and reliability, not a claim that nothing can be built.

    
What the validator caughtTypical rules-based CPQPredictika
Applications that only some pump families are listed forOnly with care
A product rule per family and application. It works, but the table has 12 families and 23 applications, and every update to the brochure is another set of rules to maintain.		The family and the application are in one request and the whole table is checked together.
Limits that differ by family: size range, capacity, head and pressureOnly with care
Four limits per family, each its own rule or lookup that has to be kept in step with the published figures.		Every family limit is looked up from the family and checked on every call.
Head that adds up when pumps run in seriesOnly with workarounds
The needed head has to be compared with the number of pumps times the family maximum, so it needs a calculated field and a rule on it.		The head the pumps give is computed and compared with the duty on every call.
A lining that does not exist on an unlined all-metal pumpOnly with workarounds
The condition depends on a choice on one line and a property of the family on another, and a missing match is usually caught only at the end.		All choices are in one request, so the conflict is found whichever order they arrive in.
A stated capacity that must match the familyOnly with care
A stated figure is a free-entry field; a rule can compare it with a looked-up value, but someone has to write and maintain that comparison.		The stated figure travels with the selection and is compared with the family's capacity on every call.
Every problem returned in one answerOnly with workarounds
Rules tend to fire as the selection is saved or a step is completed, so a rep often fixes one error and meets the next.		All findings come back together, whatever order the choices arrived in.

Every rule is checked on every call, in any order the choices arrive; one problem never hides another. Blocking findings stop the quote; approval findings need a person to sign off; everything else is computed.

The text of the narrated walkthrough, step by step.

    
    
      
  1. Welcome to a demo of Predictika's Validator. An AI sales agent prepares a selection for a Warman horizontal slurry pump: the pump family, the application, the discharge size, and more. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the published pump family limits and application table and returns a verdict, every reason and the figures it computed.
    2. 
      
  2. I will start with the first request by the agent.
    3. 
      
  3. The agent says. Please select a Warman XU slurry pump for SAG mill discharge, with a 350 mm discharge, a flow of 3,000 m3/h. The quote states that this pump family is rated for up to 3,000 m3/h. The rest of the request is on screen.
    4. 
      
  4. Before it goes out, the agent calls the validator.
    5. 
      
  5. Blocked, with five findings, all in one answer. This application is not listed for the selected pump family in the Warman horizontal slurry pump application table. The discharge size of 350 mm is above the 300 mm largest size of this pump family. The duty flow of 3,000 m3/h is above the 2,275 m3/h maximum capacity of this pump family. The other two are on screen.
    6. 
      
  6. The validator returned five blocking findings in one answer. A check that reads one field at a time would pass most of this; it shows only when the choices in the quote are checked against each other.
    7. 
      
  7. What this shows: for limits that differ by family: size range, capacity, head and pressure, a rules-based CPQ is error-prone for this.
    8. 
      
  8. Now the agent resubmits.
    9. 
      
  9. The corrected request. It changes the pump family to Warman MCR and the stated family capacity to 22,700.
    10. 
      
  10. It calls the validator again.
    11. 
      
  11. This time the validator clears it.
    12. 
      
  12. All five earlier findings are cleared, and the validator's figure matches the quote.
    13. 
      
  13. Five problems caught in one call, fixed in one pass, and a clean quote. That is the value of Predictika's validator: catching mistakes before they reach the customer.
