1 General introduction KDZ model fixed diesel engine self-priming pump is a new product with innovative structure which is developed on the basis of repeated researches of foreign same kind of technology; it is a perfect combination of single cylinder diesel engine and self-priming pump and can be manual an automatic operation. The diesel engine self-priming pump combines self-priming and no-plugging blowdown and adopts axial reflux external mixing method; with the unique design of pump body and impeller passage,Website:http://www.hpumpequipment.com, it can work like other clean water self-priming pump without bottom valve installation or filling leading liquid and also can carry out the suction and discharge of liquid with foreign matters like large-size particles and long fiber; it is the most ideal diesel engine self-priming pump which can be widely used in municipal sewage, drought resisting, pond culture, light industry, paper making, textile industry, food, chemical industry, electricity industry, fiber, sizing agent and the transportation of hybrid suspension medium. Compared with domestic same kind of products, the diesel engine self-priming pump has advantages like simple structure, good self-priming ability, good sewage drainage capacity, high efficiency, energy saving, easy operation and maintenance and is the first innovation in the field of sewage drainage pumps. All technical performance indexes are in domestic leading position, reaching International advanced level and has a wide market application and development prospect.2.Application fields:① environment temperature≤50℃, medium temperature≤80℃, for special requirements, it can reach 200℃. ② PH value of medium cast iron is 6-9, stainless steel is 2-13, for lined with fluoroplastics is 1-13 ③ medium unit weight cannot exceed 1240kg/m3. ④self-priming height cannot exceed regulated value 4.5-5.5m, total length of suction inlet pipe ≤10m. ⑤ Suspension particles' traffic ability diameter is 50% of pump entrance diameter, while the length fiber is 5 times of pump entrance diameter.3.
