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

An AI sales agent prepares an order for a plant or building-services engineer who needs a Grundfos CR or CRN vertical multistage pump: the pump size and number of stages, the motor, the flange connection, the duty pressures and the liquid temperature. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the pressure, motor and temperature limits in Grundfos's public data booklet and returns a verdict, every reason and the figures it computed.

Scope: Grundfos CR and CRN vertical multistage pumps (50 Hz, IEC): pump type by size and stages, standard motor, flange connection, operating and inlet pressure, liquid temperature. See everything this validator covers

This validator models orders for Grundfos CR and CRN pumps against the tables in Grundfos's public CR, CRI, CRN data booklet (50 Hz, read October 6, 2026), not just the scenarios shown below.

  • Pump type — CR pumps in sizes 1, 3, 5, 10, 15, 20, 32, 45, 64, 95, 125, 155, 185, 215 and 255, and CRN pumps in sizes 32 to 255. Each size is offered only with the stage counts (and reduced-diameter impeller variants) the booklet lists.
  • Motor — the booklet gives one standard motor power for each pump type; any other motor power is reported.
  • Flange connection — oval flange (BSP) or DIN flange; the oval flange is not offered on every type.
  • Pressure — the outlet pressure (inlet pressure plus the pump differential pressure) is compared with the maximum operating pressure for the pump type and connection, and the inlet pressure with the maximum permissible inlet pressure. For CRN sizes 32, 45 and 64 a high-pressure version is listed on request, so an outlet pressure between the standard maximum and that limit needs approval.
  • Liquid temperature — the standard range, the wider range Grundfos lists on request (to 180 °C, oils to 240 °C, down to −40 °C), and temperatures beyond that.

Any Grundfos CR or CRN order that touches these tables is in scope — not only the scenarios pictured here. Not covered: prices (the booklet lists none, so there is no price build-up or line-item quote), CRI pumps, CRN sizes below 32, the CR 1s variant, shaft-seal pressure and temperature limits at high pressure, liquid and material compatibility, 60 Hz pumps, motor voltage and make, and options beyond the booklet's tables. Pumps are selected for a duty point, so a check against these tables is a first filter, not a final selection.

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
A limit that depends on several choices at onceOnly with workarounds
The pressure limit varies with the pump size, the number of stages and the flange, so each combination needs its own rule or lookup, and a combination left out is never checked.		The limit for the exact combination is looked up and compared on every call.
A figure computed from two inputsOnly with care
The outlet pressure is the inlet pressure plus the differential pressure; it has to be calculated before any rule can compare it with a limit.		The outlet pressure is computed and checked in the same pass as everything else.
A standard component fixed by the pump typeOnly with care
The standard motor depends on the size, stages and impeller variant; a rule or table per type has to be kept in step with the booklet.		The motor ordered is compared with the standard motor for the exact pump type.
Not offered versus available on requestOnly with workarounds
Rules usually allow or block; a CRN outlet pressure above the standard maximum but within the high-pressure limit needs a person, which means a separate approval step.		The order is reported as needing approval, with the limit that applies, instead of being blocked or passed.
Every problem returned in one answerOnly with workarounds
Rules tend to fire as the order 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 an order for a plant or building-services engineer who needs a Grundfos CR or CRN vertical multistage pump: the pump size and number of stages, the motor, the flange connection, and more. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the pressure, motor and temperature limits in Grundfos's public data booklet 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 quote a CR 32-8 pump with an 11 kW motor and oval flange (BSP), for an inlet pressure of 8 bar and a differential pressure of 23 bar. It is ready to send.
    4. 
      
  4. Before it goes out, the agent calls the validator.
    5. 
      
  5. Blocked, with two findings, all in one answer. The order specifies a motor of 11 kW; the standard motor for this pump type is 15 kW. The oval flange (BSP) connection is not offered on this pump type; the DIN flange is.
    6. 
      
  6. The validator returned two 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 a standard component fixed by the pump type, a rules-based CPQ is error-prone for this.
    8. 
      
  8. Now the agent resubmits.
    9. 
      
  9. The corrected request. It changes the motor to 15 kW and the connection to DIN flange.
    10. 
      
  10. It calls the validator again.
    11. 
      
  11. Still blocked, with one finding, all in one answer. The outlet pressure is 31 bar (inlet pressure plus pump differential pressure); the maximum operating pressure for this pump type and connection is 30 bar.
    12. 
      
  12. Two findings cleared, but the change brings a different blocking finding: outlet pressure too high.
    13. 
      
  13. The agent resubmits once more.
    14. 
      
  14. The revised request. It changes the differential pressure to 22 bar.
    15. 
      
  15. It calls the validator once more.
    16. 
      
  16. This time the validator clears it.
    17. 
      
  17. The earlier finding is cleared.
    18. 
      
  18. Two problems caught in one call, fixed in two passes, and a clean quote. That is the value of Predictika's validator: catching mistakes before they reach the customer.
    19.
