Impeller
Double-suction impeller is used to reduce axial force to a minimum
The best hydraulic model for CFD optimized design with good performance
In addition to the prototype impeller, a pump body can also be used with modified impellers to adapt to different working conditions and improve efficiency.
Shell
According to the stress situation, a double volute type is used to reduce the radial force, and the bearing stress is small and the service life is long.
Easy installation, self-correcting pump cover
The relative positions of the motor and pump body inlet and outlet pipes can be changed according to the user’s site requirements.
There is no vortex in the inlet, and the operation is smooth and the loss is low.
Bearing
Grease-lubricated rolling bearings are easy to maintain, and the bearings are enlarged and have a long service life.
The tail end bearing is installed with bearing bushing and keying, which is reliable in fixation and easy to disassemble and assemble.
Shaft
The shaft is thickened, has good rigidity, runs smoothly, has a novel structure, and the rotor will not be damaged if it is reversed for a short period of time, and it is easy to change direction.
Completely sealed shaft, no contact with liquids, no corrosion of threads
The parts are guaranteed to be assembled to size, and no adjustment is required when the pump is assembled.
Base
The entire series can be equipped with a welded steel base as needed, which is impact-resistant, tough, lightweight and durable.
Shaft seal
The high-quality mechanical seal has no leakage and the mechanical seal sleeve is made of stainless steel to avoid corrosion and is easy to maintain.
Non-asbestos soft filler that meets environmental protection requirements. Injection-type soft filler with online maintenance function. No need to shut down for maintenance to avoid expensive production shutdown losses. It has low friction power consumption and no leakage.

Packing seal flushing pipe components: not installed when the inlet pressure is ≥0.03MPa
Structural design: single-stage double-suction horizontal center opening, horizontal installation, motor driven
*According to needs, XBD can be equipped with 380V, 6kV, 10kV and various protected (IP23, IP44, IP54) motors
*The supporting power below 630kW can be equipped with the Y2 series low-voltage (380V) motor. It is a new type of high-quality motor that is better and higher-grade than the Y series. It has a beautiful appearance and low noise, with a protection grade of IP54 and an insulation grade of F. Level (B-level assessment). At the same time, Y2 series motors below 315KW have installation interchangeability with Y series (IP44) motors.
- Ordering parameters that must be provided
△Pump model and user-required operating point flow and head parameters (the pump model should include the nominal diameter and rotation direction of the impeller)
△Inlet pressure (the specific value is required to determine the static pressure test pressure, whether to match the return pipe and the pump casing material. If P1 ≥ 0. 60MPa, the pump casing material must be specially configured)
△Shaft seal type (if it is equipped with mechanical seal or injected soft packing, it must be specified. If not specified, it will be delivered as packing seal)
△The direction of rotation of the pump (if it is installed in a counterclockwise direction, it must be specified. If not specified, it will be delivered in a clockwise direction)
△Motor power, voltage, protection level, insulation level, cooling method (when the motor power is >100kW, IP23 Y series motors are generally used; when the motor power is <100kW, IP44 Y series motors are generally used)
△ Equipped with a public base (the standard configuration is: when the motor power P<100kW and the inlet diameter DN1≤300, it is equipped with a public base, otherwise it is not equipped. Therefore, if P>100kW, DN1>300 requires a public base, it must be specified)
△Materials for impellers, shafts and other parts (if not specified, they will be delivered with standard configuration)
△Anchor bolts (if not specified, they are not suitable)
△Medium temperature (if not specified, the medium will be delivered at normal temperature)
- Selection instructions:
△User ordering is not limited by the parameters listed in the sample performance curve and technical data table. The parameters listed in the sample are only special typical point parameters for user selection reference. The company can provide products according to the flow and head operating points required by the user’s design.
△If the performance parameters are similar, the standard impeller pump type (M type) and the high-speed pump type are generally preferred.
△If the flow and lift parameters required by the user are not in the large flow and low lift working condition area of the product, the motor power can be calculated and determined based on the actual working point and appropriately reduced.
- If you have special selections beyond the sample content or if you have any questions about the sample content, please consult directly.
- Special attention points: In order to facilitate user installation, the base structure has been improved after the upgrade. If the customer has made the foundation according to the basic installation dimensions of the previous version of the sample, please indicate it in the order; if the user has made the foundation according to the dimensions of other manufacturers For a good foundation, please attach the dimensional drawing to the order; if the foundation has not been made yet, please inform the user to make the foundation based on the sample dimensions of this version or the basic dimensional drawing provided by the technical center.
