法国采购需求：电力、建筑供暖、水利、污水处理、石油化工、矿山冶金

We're looking to source two units of each of the following pump types tailored for specific applications. First up, we need a pump with a 22 kW power rating and a flow capacity of about 44 L/s, ideally with self-cleaning capabilities. Additionally, we're interested in a model that operates efficiently between 12 to 41 m head, suitable for handling fibrous and contaminated wastewater. Lastly, we require a robust pump with a power rating of 47 kW, designed for abrasive environments, offering a high performance at a flow rate of roughly 245 m³/h across a range of 38 to 97 m head. Please provide your best equivalents for these requirements at your earliest convenience.
