Predictika · Fluid coupling quotes
An AI sales agent prepares a quote for a constant-fill turbo coupling: the coupling type, the size, the motor power and speed, the driven application, and options such as centrifugal valves. Before the quote goes out, the agent sends it to Predictika, which checks it against a declarative model of what fits what and returns a verdict, every reason and the figures it computed.
This validator models turbo coupling quotes, not just the scenarios shown below.
Any turbo coupling quote that touches these rules is in scope — not only the scenarios pictured here. Not covered: fill-controlled types and diesel types. Type names, size ranges and option names follow the public Voith website. The motor capacity of each size, the application approvals, the start frequency and reversing rules and the monitoring threshold are modeled from comparable fluid couplings, not published by Voith. No prices are modeled.

What this means
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 caught | Typical rules-based CPQ | Predictika |
|---|---|---|
| Types that are offered only in some sizes | Only with workarounds A compatibility table or one rule per type and size range, edited again whenever the range changes. | The type and the size are checked together on every call. |
| A motor capacity that depends on the size | Only with care Each size transmits a different power at each speed, so a rule must look up the capacity of the selected size and compare it with the motor. | The capacity is looked up inside the model and compared on every call. |
| Options that depend on the application | Only with care An armored-face conveyor needs the valve version while a belt conveyor needs a delay chamber, so each application is its own rule across fields. | The application and the options are fields of one request and every rule is checked in the same pass. |
| Approvals for duty the type is not built for | Only with workarounds Frequent starts, reversing duty and a plain type on a belt conveyor each need a person to confirm, and each is a separate rule. | Every approval is raised in the same pass, alongside any blocking finding. |
| Every problem returned in one answer | Only 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. |
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.
| 1 | Size 400 is not one of the modeled coupling sizes (154, 206, 274, 334, 422, 487, 562, 650, 750, 866, 1000, 1,150). |
| 2 | Type T starts at size 154. |
| 3 | Types TV and TVV are available from size 274; the quote has size 206. |
| 4 | Type TVVS is available from size 422; the quote has size 334. |
| 5 | Type TVS is offered in size 650 only; the quote has size 562. |
| 6 | A motor of 6,500 kW is outside the 1 kW to 6,000 kW range of these couplings. |
| 7 | A 6,500 kW motor at 1,500 rpm is above the modeled capacity of size 1,150 (6,000 kW). |
| 8 | A 160 kW motor at 1,500 rpm is above the modeled capacity of size 334 (105 kW). |
| 9 | A 100 kW motor at 1,000 rpm is above the modeled capacity of size 422 (75 kW). |
| 10 | Motor speed 1,200 rpm is not modeled; use 1,000 or 1,500 rpm. |
| 11 | The centrifugal-valve option (TV..F) is offered with TV, TVV and TVVS only. |
| 12 | The dynamic-refill option (TV..Y) is offered with TV, TVV and TVVS only. |
| 13 | Centrifugal valves (F) and dynamic refill (Y) cannot be combined. |
| 14 | Armored-face conveyor drives need the centrifugal-valve (TV..F) version. |
| 15 | A water-filled coupling at -5 C ambient needs the antifreeze option. |
| 16 | A 500 kW drive needs thermal monitoring (OnSens.SmarTemp, BTM or MTS). |
| 17 | The TVVS softens start-up for up to 45 s; the quote needs 60 s. |
| 18 | A plain T coupling has no delay chamber; a belt conveyor normally uses TV, TVV or TVVS. |
| 19 | 8 starts per hour; TVS has the higher thermal capacity for frequent starts. |
| 20 | Biodegradable fluid on a 600 kW drive needs a thermal rating check. |
