Fire Pump Self-priming Type

Diesel engine self-priming pump using range
(1), the environment temperature is 50 ℃ or less, the medium temperature of 80 ℃ or less and special requirements of up to 200 ℃. 
(2), medium PH cast iron material for 6-9, stainless steel is 2-13, fluorine plastic lined with 1-13
(3), medium heavy no more than 1240 kg/m3. 
E. 4.5-4, self-priming height should not exceed 5.5 meters, the total length of suction pipe for 10 meters or less. 
(5), 50% of the capacity of pump diameter suspended particles, fiber length is 5 times of pump diameter. 
3, running conditions
1. The sea dials high, at an altitude of 2500 meters or less need to increase engine power.
2. The environment temperature: - 25 ~ 55 ℃
3. The air relative humidity: 9-95%
4. The seismic intensity: 7 degrees

Technical Advantage :

1. T series self-priming pumps are designed for economical & trouble-free operation in handling solids-laden liquids and slurries. 

2. T Series pumps are designed for economical & trouble-free operation in handling solids-laden liquids and slurries. Pumps feature a large volute design which allows them to re-prime automatically in a completely open system without the need of suction or discharge check valves. And this is workable with the pump only partially filled with liquid and completely dry suction line. 

3. Pumps will be able to handle up to 75mm spherical solids, depending on pump models. In case that pump shaft or bearings need service or repair, the entire rotating assembly can be removed without disturbing pump casing or pipelines. 

4. Rotating assembly is sealed with an O-Ring, allowing for external adjustments of clearance
