Predictika · Circulator pump orders

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

An AI sales agent prepares an order for high-efficiency circulator pumps with a model, a supply voltage, a pipe size and the conditions the pumps will run in. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the data sheet limits and returns a verdict, every reason and the figures it computed.

Scope: Wilo-Stratos MAXO circulators, US 60 Hz line (14 models, 1 1/4 in. to 3 in. connections): supply voltage, pipe size, minimum suction head, fluid and ambient temperature and system pressure. See everything this validator covers

This validator models orders for the Wilo-Stratos MAXO US 60 Hz circulators listed in the Wilo submittal data sheet, not just the scenarios shown below.

  • Models and supply voltage — the 14 models 1.25x3-15, 1.25x3-20, 1.25x3-25, 1.25x3-30, 1.25x3-35, 1.25x3-52, 1.5x3-52, 2x3-20, 2x3-25, 2x3-35, 2x3-50, 3x3-20, 3x3-40 and 3x3-52. Four of them (1.25x3-15, 1.25x3-20, 1.25x3-25, 1.25x3-35) and the 2x3-50 can run on a 115 V or a 230-240 V supply; the other nine are 230-240 V only.
  • Pipe connections — each model has flanges of one size (1 1/4, 1 1/2, 2 or 3 in.), and the pipe size on the order must match.
  • Suction head and operating limits — the inlet pressure must be at least the minimum suction head the data sheet gives for the model at the fluid temperature; fluid from 14 to 230 degrees F, ambient from 14 to 104 degrees F and a maximum operating pressure of 145 PSI.
  • Order summary — article number, weight per pump and the total weight for the quantity ordered.

Any order for these Stratos MAXO models that touches these rules is in scope — not only the scenarios pictured here. Not covered: prices (the data sheet has none, so this validator produces no price build-up or line-item quote), duty-point selection (flow and head curves), the CIF communication modules and accessories, other Wilo pump families and the 50 Hz or flanged-variant data sheets. Assumption: the data sheet gives the minimum suction head at 122, 203 and 230 degrees F; the validator uses the 122 degree value up to 122 degrees F, the 203 degree value above that up to 203 degrees F and the 230 degree value above 203 degrees F (the next listed temperature up).

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 that run on 115 V and models that do notOnly with care
Voltage is an option on one line and the model is another, so each of the nine 230 V-only models needs its own availability rule, and a new model is a new rule.		The model and the supply voltage travel in one request and every pairing is checked together.
Minimum suction head that depends on model and fluid temperatureOnly with workarounds
The required head is a lookup by model group and temperature band, compared with a number the rep types in; that means a table plus a validation rule per model group, and a boundary such as 203 versus 204 degrees F is easy to get wrong.		The required head is computed from the model and temperature on every call and compared with the inlet pressure, with the boundaries tested.
Pipe size that must match the pump flangesOnly with care
A product rule per model and pipe size; it works, but each new model adds more rules to maintain.		The model and pipe size are in one request and checked together 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 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 high-efficiency circulator pumps with a model, a supply voltage, a pipe size and the conditions the pumps will run in. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the data sheet limits 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 order 4 Stratos MAXO 3x3-40 circulators on a 115 V supply for 3 in. piping. The fluid runs at 180 degrees F, the ambient temperature is 85 degrees F, the system pressure is 90 PSI and the inlet pressure at the pumps is 15 PSI. 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. Stratos MAXO 3x3-40 is offered only for 1~230-240 V supply; the order specifies a 115 V supply. The inlet pressure of 15 PSI is below the 21.3 PSI minimum suction head this pump needs at a fluid temperature of 180 degrees F.
    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 minimum suction head that depends on model and fluid temperature, a rules-based CPQ can do this only with workarounds.
    8. 
      
  8. Now the agent resubmits.
    9. 
      
  9. The corrected request. It changes the supply voltage to 230 V and the inlet pressure at the pumps to 25 PSI.
    10. 
      
  10. It calls the validator again.
    11. 
      
  11. This time the validator clears it.
    12. 
      
  12. Both earlier findings are cleared.
    13. 
      
  13. Two 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.
