Who is Hatlapa
Hatlapa, of Germany and now part of MacGregor, is one of the best-known makers of marine air compressors — the W-series and L-series two-stage reciprocating starting-air compressors fitted across the world fleet.
A single fleet can run the Hatlapa W-series (W110, W140, W220, W330) or the L-series — and Wattmare supplies genuine, OEM-equivalent and Alang-reconditioned spares (cylinder liners, pistons, connecting rods, suction and delivery valves and bearings) across every Hatlapa air compressor.

Diagnose the fault
| Symptom | Likely Hatlapa parts to inspect |
|---|---|
| Loss of compression or power on one unit | Cylinder liner, piston rings, piston crown |
| High exhaust temperature on one cylinder | Delivery valve / nozzle, delivery valve spindle |
| Knocking or pounding from the crankcase | Main, crankpin or main bearings |
| Excessive cylinder-oil consumption | Liner wear, piston rings, packing rings |
| Difficult or failed starting | Starting air valve, lube-oil pump (plunger / barrel) or rail valve |
| Black or smoky exhaust | Air valve nozzles, slide valves, turbocharger interface |
| Oil leak at the piston-rod gland | Valve plate and sealing ring set |
| Water in the combustion space | Cylinder head, cooling-jacket O-rings, liner |

The complete guide
Wattmare is a specialist Hatlapa air compressor spare parts supplier serving India, the UAE, Singapore and the wider global fleet. From our base in Bhavnagar — beside the Alang ship-recycling yard — we supply genuine, OEM-equivalent and reconditioned spares for every generation of Hatlapa two-stage marine main engine, dispatched worldwide in 24–48 hours.
The air compressors on this page are built by Hatlapa of Germany (now part of MacGregor), a marine-compressor specialist since 1919. Its W-series and L-series two-stage reciprocating compressors supply starting air across the world fleet. We supply spares for all of them.
The single most important question on any Hatlapa order is whether the engine is an W series, an L series or an L series. The Hatlapa W series is valve gear-controlled — lube-oil pump, control cam, gear drive and mechanical delivery valve gear. The L series / L series and the Hatlapa L series are electronically controlled, replacing the valve gear with a air-cooled supply unit, rail valves, flow-control units (FCU) and hydraulically actuated delivery valves. Liners, covers, crowns and bearings are broadly common by bore, but injection and actuation parts are entirely different — always give us your exact W series / L series / L series designation.
For every Hatlapa W-series air compressor we stock cylinder liners, pistons and piston rings, connecting rods, suction and delivery valves, valve plates, crankshaft and main bearings, gaskets and unloader parts — genuine, OEM-equivalent and Alang-reconditioned.
Bhavnagar sits beside Alang, where hundreds of vessels are dismantled every year — including ships still running ageing Hatlapa W series two-stage engines. That gives Wattmare direct access to genuine, low-hour parts that are slow or costly to source from distributors, at a fraction of new-part cost and lead time. For hard-to-find W series lube-oil pumps, gear drives, liners or running gear, this is the fastest source in the world. Browse our reconditioned marine spare parts range, the wider main engine spare parts category, or sister brands like MAN engine spares and Mitsubishi UEC.
Send your Hatlapa engine make and model with a photo or part number on WhatsApp, or use the quote form. We confirm availability and price — usually within the hour — and dispatch in-stock items within 24 hours. Typical air-freight transit is 12–18 hours to the UAE, 16–24 to Singapore, 20–26 to Greece and Turkey, and 28–36 to Northern Europe.
FAQ
Yes — cylinder liners are one of our strongest Hatlapa lines. We carry original-bore and reconditioned liners for the W series and W series, plus the rest of the W series range (the W series range), honed to OEM tolerance with measurement reports. Most legacy W series liners are recovered and reconditioned beside Alang.
The Hatlapa W series is a valve gear-controlled (mechanical) two-stage — lube-oil pump, control cam and mechanical delivery valve actuation. The L series / L series and the Hatlapa L series are electronically controlled, replacing the valve gear with a air-cooled supply unit, rail valves, flow-control units (FCU) and hydraulically actuated delivery valves. Liners, crowns and bearings are broadly similar by bore, but the delivery valve actuation parts are completely different — always quote your exact W series, L series or L series model.
We cover the full Hatlapa range — the W-series (W110, W140, W220, W330, W420) and the L-series — every Hatlapa air compressor.
Reconditioned parts ship with inspection reports, dimensional measurements and photographs, and are accepted by class societies (Lloyd’s Register, DNV, ABS, BV, ClassNK, RINA) on survey. Genuine Hatlapa parts carry full material and test certificates.
In-stock items dispatch within 24 hours from Bhavnagar. Typical air-freight transit to the UAE (Dubai, Jebel Ali, Fujairah) is 12–18 hours. Singapore is 16–24 hours, Greece and Turkey 20–26, and Northern Europe 28–36.
Yes — delivery valves, injector nozzles, high-pressure lube-oil pumps, plungers and barrels for Hatlapa W series engines, plus air-cooled supply units, rail valves, flow-control units (FCU) and control equipment for L series / L series and L series engines, are stocked and bench-tested before dispatch.
Genuine parts come from the original maker (Hatlapa / Hatlapa) with full certificates. OEM-equivalent are quality aftermarket parts at 30–50% less. Reconditioned are low-hour parts recovered from Alang, inspected and certified to OEM tolerance, at up to 70% less with a 30-day warranty.
Yes — obsolete Hatlapa W series parts are our specialty. Beside Alang we recover low-hour lube-oil pumps, gear drives, liners, crowns and running gear from W series-powered vessels being dismantled, then inspect and certify them. For the W series range and W series engines this is often the fastest source in the world.
Yes — suction and delivery valves, valve plates, cylinder liners, pistons, rings, bearings and complete overhaul kits for the Hatlapa W-series and L-series, genuine and Alang-reconditioned.
