An AI sales agent's Universal 2 pump selection, checked before it goes out

An AI sales agent prepares a pump selection for a food, dairy or process plant: a Waukesha Cherry-Burrell Universal 2 Series positive displacement pump, with the model, the flow and differential pressure the process needs, the speed, the product temperature and rotor clearance, the port size and type, rotors, seals and Tru-Fit drive, and the nominal capacity it states. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the figures SPX Flow publishes for the series and returns a verdict, every reason and the figures it used.

Scope: Waukesha Cherry-Burrell Universal 2 Series pumps, models 006-U2 to 370-U2: published speed, capacity, pressure, temperature, rotor clearance, port and drive rules. See everything this validator covers

This validator models one Universal 2 Series pump selection at a time, based on the figures on the public SPX Flow Universal 2 Series product page, not just the scenarios shown below.

  • Model rows — the 14 models the page lists (006, 015, 018, 030, 040, 045, 060, 130, 180, 210, 213, 220, 320 and 370), each with its speed range, nominal capacity, maximum differential pressure and the port sizes it is offered with.
  • Duty — the speed against the model's range, the flow the process needs against nominal capacity, and the differential pressure against the rating. On models 045, 180 and 210 the page says to contact application engineering for higher pressures, so a higher pressure goes to a person; on every other model it is blocked.
  • Temperature and rotor clearance — the -40 to 300 degree Fahrenheit range, standard rotor clearance up to 180 degrees, and the hot clearance option for up to 300 degrees.
  • Ports, rotors and drive — port size by model, male NPT ports (listed for models 006 to 220 only), 150 lb flanges (optional on 006 to 220, standard on 320, not listed for 370), single wing rotors for fluids with discrete particulates, Tru-Fit drives of 1/2 to 60 horsepower, and the nominal capacity the quote states, which must equal the model's listed capacity.

Any Universal 2 pump selection that touches these rules is in scope — not only the scenarios pictured here. Not covered: prices (SPX Flow publishes none for these pumps, so this page shows no price build-up), other Waukesha Cherry-Burrell series, Lightnin mixers and other SPX Flow products, material and seal compatibility with a particular product, and real-world performance, which depends on the fluid and the installation.

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
Per-model limits on speed, capacity and pressure across 14 modelsOnly with workarounds
Each model has its own speed range, nominal capacity and pressure rating. A rules-based CPQ needs a compatibility table or one rule per model, and every product page change means editing them.		The model and the duty arrive in one request and are matched to the published row on every call.
Pressure above the rating: approval on three models, blocked on the restOnly with workarounds
The same overshoot is a hard stop on most models and a call to application engineering on three, which a typical rule set treats uniformly.		The model decides whether the finding is a block or an approval, and both come back together.
Product temperature that depends on the rotor clearanceOnly with care
Standard clearance stops at 180 degrees Fahrenheit and the hot option at 300, so the check is two thresholds that depend on an earlier choice.		Temperature, clearance and the limits are compared together, in any order.
Port size and port type that depend on the modelOnly with care
Which sizes a model has, and which of male NPT and flanges it is listed with, are two more per-model tables.		Port size and type are compared with the model's row on every call.
Every problem returned in one answerOnly with workarounds
Rules tend to fire as the quote 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.

    
1A speed of 601 rpm is above the 600 rpm top of the speed range for this model.
2A speed of 701 rpm is above the 700 rpm top of the speed range for this model.

The text of the narrated walkthrough, step by step.

    
    
      
  1. Welcome to a demo of Predictika's Validator. An AI sales agent prepares a pump selection for a food, dairy or process plant: a Waukesha Cherry-Burrell Universal 2 Series positive displacement pump. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the figures SPX Flow publishes for the series and returns a verdict, every reason and the figures it used.
    2. 
      
  2. I will start with the first request by the agent.
    3. 
      
  3. The agent says. Please quote a Waukesha Cherry-Burrell Universal 2 Series pump, model 040-U2, with 2-inch sanitary clamp ports, running at 500 rpm to move 90 GPM against 200 psi of differential pressure. The product is at 140 degrees Fahrenheit, and the pump has standard rotor clearance, twin wing rotors, single mechanical seals and Buna-N O-rings. 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 process needs 90 GPM; this model has a nominal capacity of up to 45 GPM. A differential pressure of 200 psi is above the 150 psi this model is suitable for. The quote states a nominal capacity of 90 GPM; the model is listed at 45 GPM.
    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 pressure above the rating: approval on three models, blocked on the rest, a rules-based CPQ can do this only with workarounds.
    8. 
      
  8. Now the agent resubmits.
    9. 
      
  9. The corrected request. It changes the model to 060-U2 and the port size to 2.5.
    10. 
      
  10. It calls the validator again.
    11. 
      
  11. This time the validator clears it.
    12. 
      
  12. All three earlier findings are cleared, and the validator's figure matches the quote.
    13. 
      
  13. Three 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. Now you can try the other scenarios yourself.
    14.
