Single Stage End Suction Chemical Pump with Horizotal Structure (ASP5020) --Sanlian/Kubota

Model NO.: ASP5020 Working Pressure: Middle Pressure Pump Position of Pump Shaft: Horizontal Pump Mounting Height: Suction Centrifugal Usage: Pumps Head: 160m Export Markets: Global Specification: CE HS Code: 8413709990 Impeller Number: Single-Stage Pump Influent Type of Impeller: Single Suction Pump Pump Casing Combined: Horizontal Split Pumps Impeller: Closed Capacity: 2~2000m³/H Work Pressure: 2.5MPa Trademark: Sanlian/Kubota Origin: Anhui, China
ASP5020 series standard Chemical Pump is a Centrifugal Pump, which includes horizontal, Single Stage, single suction, volute casing, foot-mounted, cantilever type.
The pump is designed based on the SO2858 "End-suction centrifugal pumps Designation,nominal duty point and dimensions", and GB5656 "Technical specifications for centrifugal pumps(Class II)".
The pump is reliable, steady and efficient in hydraulic performance, and comply with International standards with simple structure and easy maintenance.
Sealing system includes packing seal, single mechanical seal, double mechanical seal and tandem mechanical seal according to different working conditions.

Application Area
Especially applied in: Refinery, Chemical and Petrol-Chemical Industry, Power plant, Sugar factory
Transmit liquid that is low temperature or high temperature; liquid that is neutral or corrosive; liquid that is clean or includes solid particles.

Performance Range
Specification: DN 32~300mm
Capacity: Q 2~2000m³/h
Head: H ~160m
Work pressure: P ~2.5Mpa
Work temperature: t -80~+300ºC

Structural Characteristics
Bearing support,shaft,sealing box and impeller form an installation module,which can be changed among different pumps in order to save the holding cost of spare parts.In the meantime,after dismantling separable coupling,there is no need to dismantle pipeline and motor before disassembling the installation module formed by Bearing support,shaft,sealing box and impeller.
(1) Pump casing
Single volute and double volute structure shall be designed on the pump casing,with interchangeable impeller ring on the pump casing to protect pump casing from abrasion.And pump casing shall also be designed with the structure of heating jacket.
(2) Flange position
Inlet flange is horizontally suctioned,outlet flange is radially upwards.
(3) Hydraulic and axial force balance
Performance curve is stable with low cavitation and high efficiency,and this characteristic shall be kept like this even when load is not enough.
(4) Bearing and lubrication
Single-row ball-bearing and thin oil lubrication shall be applied on the bearing;bearing sealing is labyrinth seal;oil level is automatically controlled by a constant oil cup.
(5) Shaft seal
Mechanical seal box or packing seal box shall be applied on the shaft seal,and seal box can be cooled or heat retaining,shaft seal can be cooled or washed.
(6) Flange pressure rating and rotation direction
Flange design pressure rating is PN16 and PN25,and ANSI125,150 is also applicable.
The pump rotates clockwise from the direction of motor end.
