污水泵属于无堵塞泵的一种，具有多种形式：如潜水式和干式二种，目前最常的潜水式为WQ型潜水污水泵，最常见的干式污水泵如PW型卧式污水泵和WL型立式污水泵二种。主要用于输送城市污水，粪便或液体中含有纤维。纸屑等固体颗粒的介质，通常被输送介质的温度不大于80℃。由于被输送的介质中含有易缠绕或聚束的纤维物。故该种泵流道易于堵塞，泵一旦被堵塞会使泵不能正常工作，甚至烧毁电机，从而造成排污不畅。给城市生活和环保带来严重的影响。因此,抗堵性和可靠性是污水泵优劣的重要因素。 和其它泵一样,叶轮、压水室、是污水泵的两大核心部件。其性能的优劣，也就代表泵性能的优劣，污水泵的抗堵塞性能，效率的高低，以及汽蚀性能，抗磨蚀性能主要是由叶泵和压水室两大部件来保证。下面分别作一介绍：
