BLACK CLAWSON Product Lines We Repair
Our engineers are trained on the full BLACK CLAWSON product range. Below are the major product families we service.
Deflaker Control Systems
Electronic controllers managing Black Clawson deflaker operation, fiber separation, and pulp consistency. Common failures include solenoid valve driver failures, loss of pressure feedback signals, and controller board thermal stress.
Refiner Drive Electronics
Motor control and variable frequency drive systems powering Black Clawson refiners used in fiber development. Repair needs include power stage faults, encoder interface errors, and overload relay calibration.
Consistency Control Modules
Precision measurement and feedback systems maintaining optimal pulp consistency in Black Clawson screening and washing operations. Typical faults are sensor drift, analog signal conditioning failures, and PID loop instability.
Screening System Logic Controllers
Programmable logic controllers governing Black Clawson screening decks, vibration motors, and bypass systems. Common issues include relay card degradation, AC motor contactor failures, and logic sequencing errors.
Pulp Flow Instrumentation
Differential pressure transmitters, level switches, and temperature sensors integrated in Black Clawson pulping lines. Faults include diaphragm rupture, electrical connector corrosion from pulp exposure, and calibration drift.

Common BLACK CLAWSON Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in BLACK CLAWSON equipment arriving at our workshop.
- ✓Solenoid valve driver transistor burnout — Black Clawson deflaker and screening systems use high-current solenoid outputs to control pulp flow gates. Thermal cycling, moisture ingress, and power supply transients cause output transistor failures, preventing valve actuation.
- ✓Consistency sensor millivolt signal loss — Black Clawson consistency probes operate in abrasive, wet pulp environments. Connector oxidation, cable jacket degradation, and sensor electrode fouling reduce or eliminate the low-level measurement signal, causing control system errors.
- ✓Refiner motor overcurrent fault code — Black Clawson refiners apply massive mechanical loads during fiber treatment. Drive overload relays trip due to bearing friction increase, fiber bridging, or worn motor windings that raise current draw above setpoint.
- ✓Relay card contact chatter and erratic output — Black Clawson PLC-based screening controllers use electromechanical relays for AC motor control and bypass valve switching. Vibration, thermal stress, and contact erosion cause intermittent switching and loss of equipment coordination.
- ✓Power supply voltage sag and controller reset loops — Black Clawson control systems draw variable current depending on solenoid and motor load states. Inadequate supply wiring or utility voltage fluctuations cause under-voltage resets, interrupting production and losing process setpoints.
- ✓Temperature sensor open circuit in pulping line — Black Clawson RTD and thermocouple sensors installed in hot pulp streams and bleaching towers suffer head corrosion, lead wire embrittlement, and transmitter input module failures from thermal shock.
