An AI sales agent's compact hydraulic power pack order, checked before it goes out

An AI sales agent prepares an order for compact hydraulic power packs of the HK 34 and HK 33 types: the motor size, the tank, the pump, the duty, the mains supply, the pressure and flow the application needs, the oil, the temperatures and the delivery flow it states. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the figures HAWE publishes in its data sheet D 7600-3 and returns a verdict, every reason and the figures it computed.

Scope: HAWE HK 34 and HK 33 compact hydraulic power packs (radial piston or gear pump, two tank sizes): pressure, flow, oil volume, fluid and temperature limits. See everything this validator covers

This validator models an order for HAWE compact hydraulic power packs of type HK 34 (1.1 kW) and HK 33 (0.8 kW), based on the figures in the public HAWE data sheet D 7600-3, not just the scenarios shown below.

  • Motor, pump and duty — the working pressure must stay within the limit the data sheet gives for the motor, the pump size (radial piston H 0.9 to H 6.5 or gear Z 2.0 to Z 6.9) and the duty: continuous operation, or load and no-load operation with idle periods. A gear pump in continuous operation above 100 bar goes to a person to confirm.
  • Flow and oil volume — the flow the application needs must not exceed what the selected pump delivers at the mains frequency (50 or 60 Hz), the usable oil volume needed must fit the standard or large tank, and the delivery flow the order states is compared with the one the validator computes.
  • Fluid, temperatures and mains — no water-containing fluids, biodegradable HEES fluids up to about 70 degrees Celsius, fluid between -25 and 80 degrees, ambient between -40 and 60 degrees. The 500 V 50 Hz and 220 V 60 Hz motor voltages go to a person to confirm.

Any HK 34 or HK 33 order that touches these rules is in scope — not only the scenarios pictured here. Not covered: prices (HAWE publishes no list prices, so this page shows no price build-up), the connection blocks, valve banks and other options, other HAWE power pack and pump types, voltage derating, and the hydraulic design of the machine itself. The data sheet remains the final authority.

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
Pressure limit that depends on the motor, the pump size and the duty togetherOnly with workarounds
The limit is a three-way lookup (two motors, fifteen pump sizes, two duties). In a typical configurator that means a large table or many rules, and the duty condition is easy to leave out.		The limit is looked up from motor, pump and duty on every call and compared with the working pressure.
Flow that depends on the mains frequencyOnly with care
The same pump delivers a different flow on 50 Hz and 60 Hz; the frequency has to be read from the motor voltage choice before the flow is compared.		The delivery flow is computed from the pump and the mains choice, then compared with the flow needed.
Several limits at once (pressure, flow, oil volume, fluid, temperatures)Only with workarounds
Each limit is its own validation rule that fires when the order is saved, so a person often fixes one error and meets the next.		All limits are checked together and every finding comes back in one answer.
Delivery flow the order states against what the pump deliversOnly with care
The delivery flow is computed from the pump and the frequency and then compared with a number typed into the order.		The flow is computed and compared on every call.

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 compact hydraulic power packs of the HK 34 and HK 33 types: the motor size, the tank, the pump, and more. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the figures HAWE publishes in its data sheet D 7600-3 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 4 HK 33 compact hydraulic power packs. The application needs 7.00 litres per minute and 2.50 litres of usable oil, with mineral hydraulic oil at 50 degrees Celsius and an ambient temperature of 35 degrees Celsius. The rest of the request is on screen. The order states a delivery flow of 7.00 litres per minute.
    4. 
      
  4. Before it goes out, the agent calls the validator.
    5. 
      
  5. Blocked, with three findings, all in one answer. The application needs 7.00 litres per minute; the selected pump delivers 6.60 litres per minute at this mains frequency. The application needs 2.50 litres of usable oil; the selected tank holds 1.45 litres. The quote states a delivery flow of 7.00 litres per minute; the selected pump delivers 6.60 litres per minute.
    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 several limits at once (pressure, flow, oil volume, fluid, temperatures), a rules-based CPQ can do this only with workarounds.
    8. 
      
  8. Now the agent resubmits.
    9. 
      
  9. The corrected request. It changes the tank to large.
    10. 
      
  10. It calls the validator again.
    11. 
      
  11. Still blocked, with two findings, all in one answer. The application needs 7.00 litres per minute; the selected pump delivers 6.60 litres per minute at this mains frequency. The quote states a delivery flow of 7.00 litres per minute; the selected pump delivers 6.60 litres per minute.
    12. 
      
  12. One finding cleared. Still blocking: flow needed above the pump delivery and stated delivery flow does not match.
    13. 
      
  13. The agent resubmits once more.
    14. 
      
  14. The revised request. It changes the pump to H 6.5 and the stated delivery flow as to 7.56.
    15. 
      
  15. It calls the validator once more.
    16. 
      
  16. This time the validator clears it.
    17. 
      
  17. Both earlier findings are 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.
    19.
