Pump Performance Data


Pump Structure
Bearing:
imported SKF of NTN bearing, which, with a reasonable configuration, can oxtend the duration of the pump.
Cooling:
The buit-in cooling system can have the pump normally work whether the motor is on or under the liquid surface. A part of the liquid is extracted to bring out the beat produced by the motor from the pump circulation to the cooling barrel and to the pump casing and, when external cooling is required, the cooling sleeve may be separated from the pump casing and individually connected to the cooling system.
Motor:
Of F class insulation, max. working temperatures 155 C, and of a protective grade IPX8 with the effective seal.
Mechanical seal:
Use high quality mechanic seal , two ways of the seal are in series with each other and individually work to separate the motor from the pump seal to provide the motor with a dual protection.
Oil chamber:
Oil can lubricate and cool the mechanical seal and realize the attached function of safety by preventing liquid from penetrating into the motor.
Impeller:
With the optimized design, the impeller wil not be blocked up when to transport liquid with its optimum flow and rate and the maximum efficiency. There are suitable impellers at choice for every point of working condition.
Pump casing:
Use the know-how of CAD/CAM to make it of max. efficiency and min wearability
Shaft:
The pump is coaxial with the motor and the sealing device on the end of the shaft preven ts against contacting with the medium to protect is from corrosion.
Installation Type
1.Auto-coupled installation
The pump is placed down along with the guide rod and automatically connected to the drainage pipeline system. Less cost for mounting and lowering the cost for repair.
2.Movable Hard Pipe Installtion
The pump is supported by its foundation, the hard pipe joint is connected to the pipeline system.
3.3.Movable Soft Pipe Installation
The pump is supported by its foundation, the soft pipe joint is connected to the outlet rubber pipe, of multiple purposes, easy to be mounted, the pump can be easily moved from one sewage well to another.
4.Fixed Dry Installation
For those pump system able to be subjected to water flood and for connecting to wet/dry well or pipeline.
5.Fixed Wet Installation
The pump is supported by its foundation and fixed on the bottom of a sewage well with the outlet connected to the pipeline, vertically mounted.
