七、设计新颖、结构独特、节约了运行管理费：采用全新内下置水润滑轴承，利用水泵出水口的高压回液，经回水管进入泵底座里的内自行润滑，不需润滑油，故不污染输送介质，并免去了定期注油的麻烦。采用进口石墨浸渍树脂轴承配镍基合金轴套与推力盘，具有耐磨性能高、摩擦系数低、不老化、抗泥沙等特点，另外轴承上还配有推力盘，能承受泵叶轮的自重推力。
7. New design, unique structure, saving operation and management fees: using a new built-in water lubrication bearing, using high-pressure return fluid from the pump outlet, through the return pipe into the pump base, self-lubrication, no need for lubricating oil, so it does not pollute the transmission medium, and avoids the trouble of regular oil injection. Imported graphite impregnated resin bearing with nickel-based alloy bushing and thrust disc has the characteristics of high wear resistance, low friction coefficient, non-aging and anti-sediment. In addition, the bearing is equipped with thrust disc, which can withstand the self-weight thrust of pump impeller.
八、密封可靠、无泄漏：轴封采用优质机械，密封摩擦副采用石墨对碳化硅或碳化硅对硬质合金，耐磨损、无泄漏、使用寿命长。
8. Reliable and leak-free seal: The shaft seal adopts high-quality machinery, and the sealing friction pair adopts graphite to silicon carbide or silicon carbide to cemented carbide, which has the advantages of wear resistance, leak-free and long service life.
九、零部件标准化、系列化、通用程度高：如电机采用Y或Y2系列B5型，属于标准通用电机，维护、保养、方便、快捷。
Ninth, parts standardization, serialization, high degree of versatility: if the motor adopts Y or Y2 series B5, belongs to the standard general motor, maintenance, convenient and fast.
十、该系列便拆立式单级双吸泵，属于本公司开发的新一代便拆立式泵，与其它厂家的便拆式泵相比有个无可比拟的特点：SLB型泵的总高度在不影响密封件便拆功能的前提下，得到极大的降低，因为只便拆机械密封件，所以泵与电机联接支架特别短，稳定性更强，而且密封便拆型泵在更换机械密封时，不管多大功率的水泵，即使现场只有一名维修工，只要他能拿得动半片连轴器，便能独立完密封件的检修工作，实现绝对便拆便维的功效。
10. This series of portable single-stage double-suction pumps belongs to the new generation of portable vertical pumps developed by our company. Compared with other manufacturers, the total height of SLB type pumps is greatly reduced without affecting the function of easy-to-disassemble seals, because only mechanical seals are easily disassembled, so the pumps have an incomparable feature. The bracket connected with the motor is especially short and more stable, and when the mechanical seal is replaced, no matter how high the power of the pump is, even if there is only one maintenance worker on the spot, as long as he can move the half-piece coupling, he can independently complete the repair work of the seals and achieve the effect of absolute easy disassembly and maintenance
