Predictika · Vertical multistage pump orders
An AI sales agent prepares an order for a vertical multistage pump: the pump model and its motor, the supply, the working pressure, the liquid temperature, the shaft seal and the pipe connection. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the published selection chart and options and returns a verdict, every reason and the figures it computed.
This validator models orders for the EVMS vertical multistage pump line at 50 Hz, not just the scenarios shown below. It uses the 209 pump and motor combinations of the selection chart.
Any EVMS order that touches these rules is in scope — not only the scenarios pictured here. The rules apply to all three material versions (EVMS, EVMSL and EVMSG), which this validator does not distinguish. Not covered: prices (no public price list, so no price build-up or line-item quote), hydraulic duty point selection from the performance curves (flow and head), 60 Hz pumps, certifications, and other EBARA pump ranges.

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 |
|---|---|---|
| Pump and motor pairing, with a pressure rating per model | Only with care The chart pairs 209 size and stage combinations with a motor and a pressure class. A rule set needs the whole table and must be kept in step with every revision of the data book. | The model, motor and pressure rating are in one request and compared on every call. |
| Shaft seal limits (pressure, temperature, rubber type) that depend on seal and pump size | Only with workarounds Each seal has its own pressure and temperature ceiling and the balanced seals differ between small and large pumps; the rules cross several lines and interact with each other. | Seal, rubber code, pressure and temperature are checked together, whatever order they arrive in. |
| Pipe connections offered only on some sizes and pressure classes | Only with care Availability depends on pump size and pressure class, so a rule per connection and per size group has to be written and maintained. | The connection is checked against the size and pressure class of the chosen model on every call. |
| Temperature bands that need the manufacturer to be contacted | Only with care A soft limit that needs a person is easy to forget when the order is built; it needs its own approval path. | The band is a rule of its own: the quote comes back as needing approval, not as a pass. |
| Every problem returned in one answer | Only 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.
| 1 | The motor on the quote is 3 kW, but the selection chart pairs this pump model with a 2.2 kW motor. |
| 2 | The quote asks for a single phase motor, but the selection chart lists no single phase version of this pump model. |
| 3 | The supply voltage on the quote is not offered for this motor; single phase motors are 230 V, three phase motors up to 4 kW are 230/400 V and above 5.5 kW are 400/690 V. |
| 4 | The oval flange connection is offered only on EVMS 1 to 20 pumps with a 16 bar maximum working pressure. |
| 5 | Victaulic and clamp connections are offered only on EVMS 1 to 20 pumps; EVMS 32 to 90 take round or loose round flanges. |
| 6 | The quote has an operating pressure of 18 bar, but this pump model has a maximum working pressure of 16 bar. |
| 7 | The quote has an operating pressure of 20 bar, but the shaft seal on the quote is rated for 16 bar. |
| 8 | The liquid is at 130 degrees C, but the shaft seal on the quote is rated for 120 degrees C. |
| 9 | The liquid temperature of 130 degrees C is in the range (-30 to -15 or 120 to 140 degrees C) where EBARA asks to be contacted before the pump is quoted. |
| 10 | The liquid is at 90 degrees C, but the shaft seal on the quote is rated for 80 degrees C. |
| 11 | The liquid temperature of -25 degrees C is in the range (-30 to -15 or 120 to 140 degrees C) where EBARA asks to be contacted before the pump is quoted. |
| 12 | The liquid is at 150 degrees C, but the shaft seal on the quote is rated for 140 degrees C. |
| 13 | The liquid temperature of 150 degrees C is outside the EVMS operating range of -30 to +140 degrees C. |
| 14 | The rubber code on the quote (EPDM or FPM) does not match the elastomer of the shaft seal on the quote. |
| 15 | The quote states a maximum working pressure of 25 bar, but the pump model has 16 bar. |
| 16 | The quote has an operating pressure of 20 bar, but this pump model has a maximum working pressure of 16 bar. |
