1: Adopt K3V112S (Kawasaki) constant power high pressure plunger pump with ultra-long service life.
2: Use skirt valve as distribution valve, there is no dead spot in design of hopper dropper, concrete drops in hopper without any resistance, which increase the efficiency of sucking of concrete cylinder.
3: Skirt valve hopper consists of skirt valve, eye plate, cutting ring, lower hopper body, the whole length of skirt valve body is 220 mm, Lengge abrasion proof layer is welded in internal flow path, repair welding can be conducted repeatedly by using D656 abrasion proof welding rod, skirt valve body can be used for ever.
4: Hydraulic system is open type single pump ( decompression + sequence ) dual loop
