Question: Do the vertical pumps need to have suction diffusers like base mounted pumps?
Answer: No they do not due to having a engineered flow pattern that does not add turbulence. Aside from not having SD’s, they do not require concrete housekeeping pads or fibration isolation pads. This design takes about 1/5 the floor space as a base mounted pump.
Another benefit to using a vertical stage pump is that instead of having mechanical seals that leak, they use a cartridge seal kit. The repair goes from four hours to about 30 minutes to changeout.
