Manufactured by Zhejiang Danau Industries Co., Ltd., this pump is widely rebranded by companies such as Erie Tools, Waspper, and Raptor. It features a forged brass manifold for strength and corrosion resistance, paired with an anodized aluminum crankcase for heat dissipation.
The solid stainless steel plungers with ceramic coating provide superior wear resistance, while the precision-ground U-shaped dual-seal assembly ensures reliable sealing under both high and low pressure. Double thrust bearings enhance stability and longevity during continuous operation.
An adjustable unloader valve is integrated into the pump head, allowing precise pressure regulation. The pump uses splash-type lubrication with SAE 15W-40 non-detergent oil, with an oil bath capacity of 550 mL.
