Abstract: A fluid transport device defining a centerline axis therethrough includes at least one rotatable member including a first portion and a second portion axially opposite the first portion. The fluid transport device also includes at least one stationary member positioned proximate the at least one rotatable member. The at least one rotatable member and the at least one stationary member define at least one stage. The at least one rotatable member defines at least one pressure balance port extending from the second portion to the first portion. The at least one pressure balance port is configured to substantially equalize a fluid pressure proximate the second portion with a pressure of a fluid proximate the first portion.

Abstract: A sealless centrifugal blood pump (10) is provided in which a rotatable impeller (64) is supported in a pump housing (12) by fluid bearings (30, 182) during operation. Rotational movement of the impeller (64) is accomplished with an inverted motor (38) for magnetically driving of the impeller (64) and maintenance of the axial running position of the impeller (64) relative to the housing (12). In an alternative embodiment, the axis of the rotor housing (18) is radially displaced relative to the axes of drive element (126) of the motor and the motor housing (130).

Abstract: A process for producing a vinyl chloride-based polymer by suspension polymerizing vinyl chloride monomer or the like while circulating a reaction mixture in a polymerization vessel by a circulating pump through a circulation line led out from the polymerization vessel to extend through a heat exchanger back to the vessel, wherein the pump comprises a conical hub (15) and an impeller comprised of a spirally shaped single blade (16) provided on the hub (15), and, during polymerization, the stirring energy (A) applied to the reaction mixture by the stirrer in the polymerization vessel and the circulating energy (B) exerted to the reaction mixture by the circulating pump in the circulation line are controlled so as to satisfy the relationships:
(A) + (B) = from 1.5 to 4.0 kW/t (1), and
(B) / [(A) + (B)] = from 0.1 to 0.6 (2).
Polymer scale is prevented from being deposited on inner surfaces of the heat exchanger, circulation piping, circulating pump or the like.Abstract translation: 一种氯乙烯系聚合物的制造方法，其通过将聚合容器内的反应混合物循环通过循环泵从聚合容器引出的循环管道循环，使氯乙烯单体等悬浮聚合而延伸通过热交换器回到 所述容器，其中所述泵包括锥形轮毂（15）和由设置在所述轮毂（15）上的螺旋形单个叶片（16）组成的叶轮，并且在聚合期间，施加到所述反应混合物的搅拌能量（A） 通过聚合容器中的搅拌器和通过循环管线中的循环泵施加到反应混合物的循环能（B），以满足以下关系：（A）+（B）= 1.5〜4.0kW / t（1）和（B）/ [（A）+（B）] = 0.1〜0.6（2）。 防止聚合物垢沉积在热交换器，循环管道，循环泵等的内表面上。

Abstract: A vertical pump (1) having spiral blades (10, 11 and 12) fixed to the distal end of the main shaft (2) thereof. One or more spiral blades (10, 11 and 12) are arranged to be well-balanced with respect to said main shaft (2) of the pump, whereby a flow passage between spiral blades is wide, of no-closure type, and thus makes the pump particularly appropriate to sewage disposal.
