Cqstart 6 Series: Engineered for Large Pump Sets and Heavy-Duty Applications
Large-site pump sets and heavy-duty diesel applications place real demands on starting equipment — the engine has to turn over reliably under load, without the starter itself becoming a point of failure. The Cqstart 6 Series spring starter is specifically rated for diesel engines in the 16–30L displacement range, matching the scale of equipment typically found in large pump installations and industrial power sets.

With a maximum pinion torque of 184Nm and maximum winding torque of 100Nm, the 6 Series is built to deliver sufficient force to start heavy-load engines smoothly, without the hesitation or partial-turn failures that under-torqued starting equipment can produce. Standard SAE mounting flanges (SAE# 1, 2, 3) support straightforward installation onto compatible engine housings, while customized interface options are available for engines that fall outside standard SAE configurations.

Durability is built into the unit's construction: excellent anti-corrosion performance protects against moisture and chemical exposure common in industrial and outdoor pump installations, while a shaking function makes it easier to rotate the flywheel manually during routine maintenance. For operators managing large pump sets where downtime has real operational cost, a starting system engineered specifically for this displacement range — rather than adapted from a smaller-engine design — is a meaningful specification difference.
