NG(H) Песчаный насос

Насосы типа NG(Н) – одноступенчатые, одностороннего всасывания, консольные, горизонтальные, центробежные шламовые насосы. Они предназначены для непрерывной перекачки самых сложных высокоабразивных шламов, которые содержат слишком большие твердые частицы, чтобы их можно было перекачивать обычными насосами. Они подходят для доставки шламов в горнодобывающей промышленности, взрывоопасных шламов при плавке металлов, дноуглубительных работ в земснарядах и руслах рек, а также в других областях. Эта серия насосов особенно подходит для условий работы с высоким расходом, высокой концентрацией и высоким напором, хорошими характеристиками NPSH и высокой стойкостью к истиранию, может широко использоваться при транспортировке высокотемпературных и сильноабразивных шламов.

Параметры материала

Code	Material #	Hardness HRC	Performance	Application
A01	KmTBCr8	≥55	Abrasion-resistant performance is about 10% less than A05	Mud & slag application
A03	KmTBNi4Cr2	≥56	Abrasion-resistant performance is about 20% less than A05	Neutral water-sand slurry and applications with lower impact load
A05	KmTBCr26	≥56	Ranks second only to A07 in abrasion-resistant performance; fair corrosion-resistant performance.	High impact load abrasion condition; PH rate ranging from 5 to 12
A07	KmTBCr15Mo3	≥59	Best abrasion-resistant performance; corrosion-resistant performance is inferior to A05	High impact load abrasion condition
A11	KmTBCrMnMo3	38-42	Mild corrosion-resistant; lower hardness; drilling and tapping operations are applicable.	Fine particles with light abrasion.
A33		≥35	Abrasion-resistant performance is close to A03; fair corrosion-resistant performance	Oxide slurry with PH rate no less than 1, like phosphor-gypsum in phosphate fertilizer plant, nitric acid, sulph-oacid and phosphoric acid, etc.
A49		≥43	Fair abrasion-resistant performance, close to A03; fair corrosion-resistant performance in media with lower PH rate.	Corrosion conditions with low PH rate, especially for flue gas and FGD devices for media of PH≥4; general suitable for lower acid condition.
A12		≥62	Higher abrasion-resistant performance than A05; fair corrosion-resistant performance; suitable for media with PH rate is 6-16, where A05 is not suitable.	High abrasive slurry with fine particles.
A61		63-68	Optimized abrasion-resistant performance than A12	High abrasive slurry with fine particles.
