Weichai Diesel Generator Set

Weichai diesel generator sets from 22 to 800 kVA, assembled and load-tested in Qingdao, China. Weichai is one of our highest-volume engine platforms, because the WP series is the easiest diesel engine to service across Africa, the Middle East and Southeast Asia: parts are stocked in every major port city, and most mechanics have worked on one. The 39 ratings in this range pair a genuine Weichai engine with a Stamford-type alternator, and each set is wired, run and load-tested in our own workshop before it is packed.

The line-up covers five engine families. The WP6D and WP7D four- and six-cylinder units handle 22–200 kVA — the sizes that suit telecom sites, shops, small factories and standby duty for buildings. The WP10D, WP12D and WP13D six-cylinder units run from 200 to 800 kVA, which is where most of our prime-power business sits: factories on 12–24 hour shifts, cold stores, mining camps, crusher plants and construction sites.

Standby or prime rating. A standby (ESP) set is rated for one hour in twelve at variable load; a prime (PRP) set runs continuously at up to 70% average load. Tell us the duty and we rate the set for it, instead of selling you the next size up.
Site conditions. Above 1,000 m altitude or 40 °C ambient, output has to be derated. Send the site data with your enquiry and we calculate the corrected rating.
Fuel quality. WP-series mechanical pumps tolerate poor diesel better than common-rail engines, but in dusty regions specify a pre-filter and water separator.
Configuration. Open skid, silent canopy or trailer-mounted; 400/230 V 50 Hz, 480/277 V 60 Hz or any voltage on request; Deep Sea, ComAp or Smartgen control panel; ATS, breaker and base fuel tank sized to your runtime.
Documentation. Ask for the engine datasheet, alternator datasheet and factory test report for the exact rating you are quoted — we send all three with the offer.

Because each set is built after the order is confirmed, the alternator, panel and enclosure are matched to your project instead of a fixed catalogue configuration. Mixed orders are common: one WP6D set for the site office and two WP13D sets for the plant, shipped in a single container.

Request a quotation: tell us the kVA or kW, standby or prime duty, voltage and frequency, and the destination port. You will get a CIF price, the engine and alternator datasheets, and a delivery date in the same reply.
