Predictika · Two-pump pressure unit orders

An AI sales agent's water pressure unit order, checked before it goes out

An AI sales agent prepares an order for a two-pump fixed speed water pressure unit: the model, single or three phase supply, the highest pressure, the liquid and ambient temperatures, and the installed motor power and current the quote states. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the published catalogue and returns a verdict, every reason and the figures it computed.

Scope: Pedrollo COMBIPRESS CB2 fixed speed pressure units (two pumps, 50 Hz): model and phase, supply, pressure, temperatures, stated power and current. See everything this validator covers

This validator models orders for the Pedrollo COMBIPRESS CB2 line of two-pump fixed speed pressure units at 50 Hz, not just the scenarios shown below. It uses the 54 models of the catalogue in five pump families (2CP, CR, FCR, MK and HT).

  • Model and supply — each model has its motor power per pump and is offered as a single phase unit (230 V - 50 Hz), a three phase unit (400 V - 50 Hz) or both; the phase and supply voltage on the quote are checked against what the catalogue lists for that model.
  • Pressure and temperature — the highest pressure must not exceed the pump body rating of the model (6 bar for 2CP 25/130, 10 bar for the other 2CP, 7 bar for CR and for FCR 80 and 100, 11 bar for the other FCR and for MK, 16 bar for HT); the liquid must be between +5 and +55 degrees C and the ambient between +5 and +40 degrees C.
  • Stated power and current — the installed motor power (two pumps) and the current drawn with both pumps running that the quote states are compared with the figures computed from the catalogue for the chosen model and supply.

Any CB2 order that touches these rules is in scope — not only the scenarios pictured here. Not covered: prices (no public price list, so no price build-up or line-item quote), choosing a model from the flow and head the customer needs (performance curves), 60 Hz units, Pedrollo variable speed booster sets and its other product ranges, and dimensions, weights and pipe connections.

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
Models offered only as single phase or only as three phaseOnly with care
Availability differs model by model across 54 models, so a rule or a table has to be written and kept in step with each catalogue revision.		The phase and supply on the quote are compared with the chosen model on every call.
A pressure rating that depends on the pump family, with exceptions inside a familyOnly with care
The rating is 6, 7, 10, 11 or 16 bar depending on the family and on a few individual models, so the exceptions are easy to miss.		The rating comes with the model and is compared with the highest pressure on every call.
Power and current figures stated on the quote that must agree with the catalogueOnly with workarounds
The stated figures come from outside the configuration, so a rule has to recompute the catalogue value for the model and supply and compare the two.		The stated figures are fields in the request; the validator blocks when they differ from what it computes.
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.

  

  

    
What this validator catches: findings from its test cases

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.

    
1The highest pressure on the quote is 8 bar, but the pump body of this CB2 model is rated for a maximum of 6 bar.
2The highest pressure on the quote is 17 bar, but the pump body of this CB2 model is rated for a maximum of 16 bar.
3The highest pressure on the quote is 8 bar, but the pump body of this CB2 model is rated for a maximum of 7 bar.
4The highest pressure on the quote is 12 bar, but the pump body of this CB2 model is rated for a maximum of 11 bar.
5The highest pressure on the quote is 11.5 bar, but the pump body of this CB2 model is rated for a maximum of 11 bar.
6The quote asks for a single phase unit, but the catalogue lists no single phase (230 V) version of this CB2 model.
7The quote asks for a three phase unit, but the catalogue lists no three phase (400 V) version of this CB2 model.
8The supply voltage on the quote does not match the unit; single phase CB2 units run on 230 V - 50 Hz and three phase CB2 units on 400 V - 50 Hz.
9The liquid temperature of 56 degrees C is outside the CB2 range of +5 to +55 degrees C.

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 two-pump fixed speed water pressure unit: the model, single or three phase supply, the highest pressure, and more. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the published catalogue 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 Pedrollo CB2 - FCR 15/3 two-pump pressure unit (three phase version) on a 400 V supply, for water at 62 degrees C in a room at 45 degrees C. The quote states 11 kW of installed motor power and 17.6 A with both pumps running. The rest of the request is on screen.
    4. 
      
  4. Before it goes out, the agent calls the validator.
    5. 
      
  5. Blocked, with three findings, all in one answer. The liquid temperature of 62 degrees C is outside the CB2 range of +5 to +55 degrees C. The ambient temperature of 45 degrees C is outside the CB2 range of +5 to +40 degrees C. The quote states 11 kW of installed motor power, but the two pumps of this model total 8 kW.
    6. 
      
  6. The validator returned three 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 power and current figures stated on the quote that must agree with the catalogue, a rules-based CPQ can do this only with workarounds.
    8. 
      
  8. Now the agent resubmits.
    9. 
      
  9. The corrected request. It changes the liquid temperature to 50 degrees C and the stated installed motor power to 8 kW.
    10. 
      
  10. It calls the validator again.
    11. 
      
  11. Still blocked, with one finding, all in one answer. The ambient temperature of 45 degrees C is outside the CB2 range of +5 to +40 degrees C.
    12. 
      
  12. Two findings cleared. Still blocking: ambient temperature outside the range.
    13. 
      
  13. The agent resubmits once more.
    14. 
      
  14. The revised request. It changes the ambient temperature to 35 degrees C.
    15. 
      
  15. It calls the validator once more.
    16. 
      
  16. This time the validator clears it.
    17. 
      
  17. The earlier finding is cleared, and the validator's figure matches the quote.
    18. 
      
  18. Three 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. Now you can try the other scenarios yourself.
