Goulds Pump 3SV13NA30 Vertical Multistage Centrifugal Pump Liquid End

The Goulds 3SV13NA30 is a Vertical Multistage Centrifugal Pump Liquid End, e-SV Series 3SV, 13 stages, less motor, with 316L Stainless Steel construction, 1-1/4 Inch ANSI raised-face flanged, in-line suction and discharge, Carbon/Silicon Carbide/Viton Mechanical Seal, for a 3 HP 3500 RPM 56C frame motor. The Goulds e-SV Series is a fabricated stainless steel vertical multistage pump: an energy saving, non-priming pump coupled to a standard premium-efficient motor, built to withstand mechanically aggressive and high temperature liquids and designed to extend uptime and reduce lifecycle costs. Its hydraulics, combined with a high-efficiency EISA compliant motor, deliver maximum efficiency. This Round-316 configuration has an AISI 316L stainless steel pump body and AISI 316L stainless steel impellers and diffusers, with AISI 316L stainless steel casing and seal plate, AISI 316 shaft. The balanced impeller design reduces axial thrust for long standard motor bearing life; a floating, self-aligning, glass filled, high temperature polymer diffuser wear ring withstands corrosive, aggressive and high temperature liquids and protects against abrasion and debris; and tungsten carbide bushings serve as the bearings, for longevity and heavy duty applications such as boiler feed. The liquid end is held in place by tie rods, and top fill plugs with air vents make it easy to remove trapped air from the seal housing. The mechanical seal, to EN 12756 (ex DIN 24960) and ISO 3069, is replaced without removing the motor, reducing repair time by up to 50%; the pump can be repaired right in the piping, the O-ring seat design allows easy outer sleeve disassembly, and a complete repair stack assembly is available for quick and efficient repair. The standard version handles liquid temperatures from -20 to 250 degrees F, this configuration is rated to 360 or 575 psi (25 or 40 bar), by casing, rotation is clockwise looking at the pump from the top down (marked with an arrow on the adapter and the coupling), and the pumps are certified NSF/ANSI 61 and 372 for drinking water. This model is a 13-stage pump: 13 impellers, 2 intermediate bearings, 10 diffusers and 2 diffusers with bushing between the initial stage and the final diffuser. It is fitted with a Carbon/Silicon Carbide/Viton mechanical seal with Viton o-rings. Suction and discharge connections are 1-1/4 Inch ANSI raised-face flanged, in-line suction and discharge. This pump is also available as a complete pump and motor unit: 3SV13NF3A10 with a 3 HP 3500 RPM 1 Phase ODP motor, 3SV13NF4C10 with a 3 HP 3500 RPM 3 Phase ODP motor, 3SV13NF3A20 with a 3 HP 3500 RPM 1 Phase TEFC motor, 3SV13NF4C20 with a 3 HP 3500 RPM 3 Phase TEFC motor and 3SV13NF4C60 with a 3 HP 3500 RPM 3 Phase TEPE (premium efficiency TEFC) motor. For 1750 RPM see 3SV13NA40. Other mechanical seals: Carbon/Silicon Carbide/EPR as 3SV13NA36, seal part 10K170, Silicon Carbide/Silicon Carbide/Viton as 3SV13NA32, seal part 10K172, Silicon Carbide/Silicon Carbide/EPR as 3SV13NA34, seal part 10K174 and Carbon/Silicon Carbide/AFLAS as 3SV13NA31, seal part 10K218. The picture is representative of the e-SV series and is not a photograph of this exact model; the number of stages, the connection type and the motor vary by model.
