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

An AI sales agent prepares an order for oil-free rotary vane vacuum pumps: the VTLF model, the supply frequency, the three-phase motor version, UL/CSA or NEMA requirements, optional variants and accessories, and the suction air, vacuum, sound, power and weight the customer needs. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the figures in public Becker data sheets and returns a verdict, every reason and the figures it computed.

Scope: Becker VTLF 2.200, 2.250, 2.250 SK, 2.400 and 2.500 oil-free rotary vane vacuum pumps: motor versions at 50 and 60 Hz, UL/CSA and NEMA, variants and accessories, suction air, vacuum, sound, power and weight. See everything this validator covers

This validator models one VTLF pump order at a time, based on public Becker VTLF US data sheets, and handles any order that uses these models, not just the scenarios shown below.

  • Models and supply frequency — the five VTLF models, each with its suction air rate at 50 Hz and 60 Hz, ultimate vacuum and sound level; the order must supply a frequency the data sheets list (50 or 60 Hz) and enough pumps to meet the suction air needed.
  • Three-phase motor versions — the numbered motor versions each data sheet lists, with their power at 50 and 60 Hz, UL/CSA listing, NEMA design and weight; a motor that is not listed for the model or the frequency is blocked, as is a UL/CSA or NEMA requirement the motor does not meet.
  • Variants and accessories — Series X, non-return valve, corrosion protection, external suction filter, sound proof box and the VARIAIR frequency inverter version (listed only for the VTLF 2.250 and 2.500); the data sheets say combinations are available on request, so any combination goes to a person, and a sound limit met only by the sound proof box goes to a person.
  • Limits and stated figure — vacuum required, sound limit, total motor power budget, total weight limit, and the total suction air the order states, which must equal the pumps' combined rate.

Any VTLF order that touches these rules is in scope — not only the scenarios pictured here. Not covered: prices (the data sheets publish none, so this page shows no price build-up), the VTLF 2.360, other Becker pump families, accessory dimensions and connection sizes, and the effect of each accessory on performance.

The AI sales agentBuilds the pump order from the conversation and says it is ready.

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
Motor versions that exist only at some frequencies (motor 2 is listed at 60 Hz only, motor 3 at 60 Hz only)Only with workarounds
A table of valid model, motor and frequency combinations, kept in step with five data sheets; a motor that is fine at 60 Hz is silently wrong at 50 Hz.		Model, motor number and frequency arrive in one request and are checked against the listed table on every call.
Suction air that depends on frequency and pump countOnly with care
The rate per pump changes with the supply frequency, then multiplies by the number of pumps and is compared with the requirement and with the figure the quote states.		The requirement, the computed total and the stated total are compared on every call.
An inverter version listed for two of the five modelsOnly with care
VARIAIR must be allowed on the VTLF 2.250 and 2.500 only, and still interacts with the other options.		The option and the model are checked together, whatever order they were chosen in.
Limits across several figures (vacuum, sound, power budget, total weight)Only with workarounds
Each limit depends on the model, the frequency and the motor, and totals depend on the pump count, so rules multiply.		Every limit is computed from the selected model, motor and quantity and compared on every call.
Every problem returned in one answerOnly with workarounds
Rules tend to fire as the order is saved or a step is completed, so a person 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
Click to expand
    
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 order has 0 pumps; at least 1 is needed.
2The order needs 300 CFM of suction air; the pumps give 0 CFM in total.
3The data sheets give figures for 50 Hz and 60 Hz supply; the order has 55 Hz.
4The data sheet for this model lists no motor number 6.
5The data sheet for this model lists no motor number 8.
6Motor number 2 for this model is not listed for the supply frequency of 50 Hz.
7Motor number 3 for this model is not listed for the supply frequency of 50 Hz.
8UL and CSA listing is required, and the selected motor is not listed as UL and CSA.
9A NEMA motor is required, and the selected motor is not a NEMA version.
10The order needs 339 CFM of suction air; the pumps give 338 CFM in total.
11The order needs 289 CFM of suction air; the pumps give 288 CFM in total.

14The order needs 22.2 in. HgV of vacuum; this model reaches 22.1 in. HgV.
15The model gives 79 dB(A) at this supply frequency; the limit is 78 dB(A) and no sound proof box is quoted.
16The model gives 79 dB(A) against a limit of 76 dB(A); the sound proof box is described on a separate data sheet, and a person should confirm it brings the level within the limit.
17The VARIAIR frequency inverter version is listed only for the VTLF 2.250 and the VTLF 2.500.
18The data sheets say possible combinations of variants and accessories are available on request; a person should confirm this combination of 2 options.
19The data sheets say possible combinations of variants and accessories are available on request; a person should confirm this combination of 3 options.
202 pumps with motors of 8.9 hp each need 17.8 hp in total; the budget is 17.7 hp.
213 pumps with motors of 25.0 hp each need 75.0 hp in total; the budget is 50.0 hp.

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 oil-free rotary vane vacuum pumps: the VTLF model, the supply frequency, the three-phase motor version, and more. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the figures in public Becker data sheets 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 2 VTLF 2.250 vacuum pumps on a 60 Hz supply, with motor version 1. The order needs 300 CFM of suction air in total and 24.0 in. The rest of the request is on screen.
    4. 
      
  4. Before it goes out, the agent calls the validator.
    5. 
      
  5. Blocked, with two findings, all in one answer. UL and CSA listing is required, and the selected motor is not listed as UL and CSA. The order needs 24.0 in. HgV of vacuum; this model reaches 23.6 in. HgV.
    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 motor versions that exist only at some frequencies (motor 2 is listed at 60 Hz only, motor 3 at 60 Hz only), a rules-based CPQ can do this only with workarounds.
    8. 
      
  8. Now the agent resubmits.
    9. 
      
  9. The corrected request. It changes the motor version to 3.
    10. 
      
  10. It calls the validator again.
    11. 
      
  11. Still blocked, with one finding, all in one answer. The order needs 24.0 in. HgV of vacuum; this model reaches 23.6 in. HgV.
    12. 
      
  12. One finding cleared. Still blocking: vacuum below the requirement.
    13. 
      
  13. The agent resubmits once more.
    14. 
      
  14. The revised request. It changes the pump model to VTLF 2.250 SK and the stated suction air as to 348 CFM.
    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. 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. Now you can try the other scenarios yourself.
    19.
