Callewaert Industries

What Callewaert Industries does

Callewaert Industries is a privately held Belgian industrial services and manufacturing company founded in 2002 and headquartered in Zwevezele (West Flanders). It operates as a federation of eight semi-autonomous divisions — Piping & Insulation, Construction & Engineering, Technical Support, Ozyx (CNC turning and milling), VPAQ Pumps, Equagaz (facility maintenance), Forzametal (sheet metal processing), and SCEN (mechanical, electrical, and software engineering) — each with its own VAT number and dedicated contact. The company serves industrial enterprises primarily in West and East Flanders across food, chemicals, recycling, flooring, insulation materials, industrial automation, and warehouse-construction sectors, with named customers including Balta, Unilin, Spiromatic, Brenntag, Geldof, Westfro, Clarebout, Ursa, Ardo, Dupont Kaas, Proviron, Galloo, and Renasci. Its proprietary technology stack centres on PITSTOP, a brand-agnostic cloud pump-monitoring application with real-time vibration, noise, and alignment telemetry; a self-developed fully automated pump test bench capable of testing up to 1,000 pump types; a Leica RTC 360-based 3D scanning and point-cloud modeling workflow in SCEN; and CIPLAN, an internal planning, skills-tracking, and digital work-order platform.

Revenue is generated through a combination of project-based industrial services (piping, insulation, metal construction, pump revision, CNC machining, technical outsourcing) and product/hardware sales (new pumps through Flowserve and Grundfos, sheet metal parts). Pricing is quote-based and not publicly disclosed. Distribution is entirely direct, with each division operating its own field-sales contact and the group coordinating complex multi-discipline projects (such as the Proviron 60+ year-old pipeline relocation, which combined Piping & Insulation, Construction & Engineering, and scanning/engineering input) from a single point of contact. The company is family-owned, co-led by Callewaert Curd and Gino De Baets, with no external funding rounds disclosed. Holding certifications including VCA, EN-1090, and ISO, with a workforce that sources describe as 100+ (homepage 2024) to 150+ (2022 news reference), Callewaert Industries positions itself as an integrated subcontractor for industrial clients in Flanders rather than a regional or international platform.

Scale indicators5 records

Recent moves8 records

Expansion highlights6 records

Direct peers

• I-care Group: Belgian-headquartered industrial maintenance and reliability services firm specializing in predictive maintenance and asset monitoring. Highly comparable to VPAQ Pumps and PITSTOP given its focus on condition monitoring, vibration analysis, and recurring maintenance contracts for industrial clients.
• Aertssen Group: Belgian multi-disciplinary industrial contractor offering heavy construction, mechanical works, transport, and maintenance services. Directly comparable to Callewaert's combination of Construction & Engineering, Piping, and Technical Support divisions serving Belgian industrial clients.

Broad incumbents

• Stork (TechnipFMC): Dutch-rooted industrial services and maintenance provider now part of TechnipFMC, serving process industry clients with mechanical, electrical, and integrity services. Comparable to Callewaert's piping, mechanical contracting, and outsourced maintenance capabilities.
• Veolia Environmental Services: Global environmental and industrial services group with significant Belgian presence in water, waste, and facility management. Comparable to Callewaert's Equagaz and Technical Support facility-maintenance offerings, though at far greater scale and with a different ownership profile.
• Equans: Multi-technical services group spun out of Bouygues, active across HVAC, electrical, mechanical, and facility management in Belgium and broader Europe. Overlaps with Callewaert's Piping & Insulation, Equagaz, and Construction & Engineering divisions, though at much greater scale and breadth.
• Bilfinger: European industrial services provider focused on process industry consulting, engineering, maintenance, and turnaround services. Comparable to Callewaert's process-industry piping, construction, and maintenance offerings, with broader geographic reach and capital base.
• Spie SA: Major European multi-technical industrial services group providing electrical, mechanical, HVAC, and process automation services. Comparable to Callewaert's full-stack industrial services model, though at vastly larger scale and pan-European scope.

Others

• KSB SE & Co. KGaA: Global manufacturer of pumps, valves, and related systems with extensive service operations. Comparable to VPAQ Pumps as a pump brand and service competitor; while KSB operates its own service network, Callewaert's Flowserve exclusivity positions it as a partner-distributor rather than a direct rival.

Regional players

• ATS Groep: Dutch industrial maintenance and technical services provider with multi-trade capabilities across mechanics, electrical, and instrumentation. Comparable to Callewaert's Technical Support outsourcing and multi-disciplinary industrial maintenance model, though operating primarily in the Netherlands.
• Verwater Group: Netherlands-based industrial services and contracting firm offering mechanical, piping, and maintenance solutions to process industries. Comparable to Callewaert's Piping & Insulation and Construction & Engineering divisions, though operating across the Benelux rather than Belgium alone.
