An AI sales agent's ProMinent gamma/ X metering pump, checked before it goes out

An AI sales agent prepares a quote for a ProMinent gamma/ X solenoid-driven metering pump: the pump type, dosing head material, seals and diaphragm, liquid end version, relay, control variant and accessories, and the duty the customer describes (flow, back pressure and suction lift) together with the capacity it states. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the figures ProMinent publishes and returns a verdict, every reason and the figures it computed.

Scope: ProMinent gamma/ X metering pumps: ten pump types, five dosing head materials, seals, liquid end versions, relay, control and accessory options, with back pressure, suction lift and flow. See everything this validator covers

This validator models one gamma/ X pump configuration at a time (with any number of identical pumps), based on the gamma/ X section of the public ProMinent Product Catalogue Volume 1 (edition 01.01.2026, read October 9, 2026), not just the scenarios shown below.

  • Pump types — 1602, 1604, 2504, 0708, 1009, 0414, 0715, 0220, 0424 and 0245, each with its published capacity at maximum back pressure, maximum back pressure (2 to 25 bar) and suction lift.
  • Options — dosing head (polypropylene, clear acrylic, PVDF, PTFE, stainless steel), seal and diaphragm version, liquid end version (non-bleed, with bleed valve, higher-viscosity, self-bleeding), diaphragm rupture indicator, relay, control variant and accessories kit.
  • Checks — which seals fit which head, which liquid end versions fit which head and pump type, the 25 bar type 2504 head limit, rupture indicator and automatic bleed valve limits, relays with fieldbus control, the accessories kit, back pressure and suction lift against the pump, and the stated capacity against the catalogue figure. A flow above the catalogue capacity, or a higher-viscosity version, goes to a person.

Any gamma/ X pump built from these options is in scope — not only the scenarios pictured here. Not covered: prices (the catalogue lists none, so this page shows no price build-up), other ProMinent pump ranges (beta, delta, Sigma, Concept, motor-driven and process pumps), spare parts, dosing systems, controllers and sensors, tube and hose sizing, and chemical compatibility.

The AI sales agentBuilds the pump 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
Which seals fit which dosing head, and which liquid end version fits which head and pump typeOnly with workarounds
These are compatibility matrices in several directions at once, and a person has to keep them in step with the catalogue footnotes.		Head, seals, version and pump type are compared together, in any order.
Back pressure and suction lift against the pump, which change with the liquid end versionOnly with care
The rating depends on the version (the self-bleeding head has its own capacity and lift figures), so it takes a rule per pump type and version.		The rating for the chosen pump and version is looked up and compared on every call.
Options that exclude each other: a relay with a fieldbus control variant, an accessories kit with PVT4, a bleed valve on type 0245Only with workarounds
Each exclusion is a rule of its own, and a rep can pick them in any order, so the error surfaces late.		They are checked with the other rules, whatever order the choices arrive in.
Flow the customer needs against the capacity of one or several pumpsOnly with care
It needs a quantity roll-up and a capacity figure per type and version, and a higher-viscosity head lowers the capacity again.		Pumps times the catalogue capacity is compared with the flow on every call.
A quote that states a capacity the catalogue does not giveNot caught
A stated figure is free text to a CPQ, so nothing compares it with the product data.		The stated figure is compared with the computed one.
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.

    
1The process back pressure is 8 bar; the chosen pump and liquid end version is rated 7 bar at most.
2The customer needs 7,601 ml/h; the catalogue gives 7,600 ml/h for the pumps at maximum back pressure, so a person should confirm the flow at the process pressure.
3The customer needs 15,201 ml/h; the catalogue gives 15,200 ml/h for the pumps at maximum back pressure, so a person should confirm the flow at the process pressure.
4The suction lift is 401 cm of water column; the chosen pump and liquid end version gives 400 cm.
5The process back pressure is 17 bar; the chosen pump and liquid end version is rated 16 bar at most.
6The 25 bar type 2504 is available only with a clear acrylic or stainless steel dosing head.

8The FDA-compliant design is offered only with PVDF and stainless steel dosing heads.
9The EC 1935/2004-compliant design is offered only with the stainless steel dosing head.
10Pumps with the vPTFE diaphragm may deliver 10 to 20 percent less than the catalogue capacity; a person should confirm the capacity.
11The vPTFE diaphragm with PTFE valve seats is offered only with the PVDF dosing head.
12Liquid end versions 0 and 1 (non-bleed) are offered only with clear acrylic, PTFE and stainless steel dosing heads, and with type 0245.
13Liquid end versions 2 and 3 (with bleed valve) are offered only with polypropylene, PVDF and clear acrylic dosing heads, and not with type 0245.
14Liquid end version 4 for higher-viscosity media may deliver 10 to 20 percent less than the catalogue capacity and is not self-priming with all feed chemicals; a person should confirm the capacity and the medium.
15Liquid end version 4 for higher-viscosity media is offered only with the PVDF dosing head.
16Liquid end version 4 for higher-viscosity media is offered only with types 1604, 0708, 0414, 1009, 0715 and 0424.
17The suction lift is 181 cm of water column; the chosen pump and liquid end version gives 180 cm.
18Liquid end version 7 (self-bleeding without bypass) is offered only for the NPT and PVT combinations, clear acrylic or PVDF head with PTFE seals.
19Liquid end version 7 is not offered for type 1602, and the catalogue lists no self-degassing data for type 2504.

The text of the narrated walkthrough, step by step.

    
    
      
  1. Welcome to a demo of Predictika's Validator. An AI sales agent prepares a quote for a ProMinent gamma/ X solenoid-driven metering pump: the pump type, dosing head material, seals and diaphragm, and more. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the figures ProMinent publishes 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 1 ProMinent gamma/ X metering pump, type 1009, with a polypropylene dosing head and EPDM seals. The liquid end is version 0 (non-bleed, without valve spring). The rest of the request is on screen. The quote states a capacity of 9,500 ml/h per pump.
    4. 
      
  4. Before it goes out, the agent calls the validator.
    5. 
      
  5. Blocked, with three findings, all in one answer. Liquid end versions 0 and 1 (non-bleed) are offered only with clear acrylic, PTFE and stainless steel dosing heads, and with type 0245. The process back pressure is 12 bar; the chosen pump and liquid end version is rated 10 bar at most. The quote states a capacity of 9,500 ml/h per pump; the catalogue capacity for the chosen pump and liquid end version is 9,000 ml/h.
    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 back pressure and suction lift against the pump, which change with the liquid end version, a rules-based CPQ is error-prone for this.
    8. 
      
  8. Now the agent resubmits.
    9. 
      
  9. The corrected request. It changes the liquid end version to Version 2 (with bleed valve, without valve spring), the flow needed in total to 9,500 ml/h, the back pressure to 10 bar and the capacity stated per pump to 9,000 ml/h.
    10. 
      
  10. It calls the validator again.
    11. 
      
  11. Not blocked, but held for a person.
    12. 
      
  12. The three blocking findings are cleared; one approval remains for a person: flow over the catalogue capacity.
    13. 
      
  13. The agent resubmits once more.
    14. 
      
  14. The revised request. It changes the pump quantity to 2.
    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.
    19.
