RHS Series Split Case Pumps

Rotech RHS Series pumps are Frame Mounted pumps available in various material of construction such as all iron, cast iron bronze fitted, all stainless steel construction.

Product Specification

Compact structure, Nice appearance, Good stability, and Easy installation
Stable running optimally designed double-suction impeller makes the axial force reduced to the minimum and has a blade-style of very excellent hydraulic performance.
Both internal surface of the pump casing and the impeller surface, being precisely cast, are extremely smooth and have a notable performance vapour corrosion resisting and a high efficiency.
The pump case is double volute structured, which greatly reduces radial force, lightens bearing’s load and prolongs bearing’s service life.

Design Specification

Outlet diameter: DN80 800mm
Max flow: 51073 GPM (11600 m3/hr.)
Max Head: 656 feet (200 m)
Max Temperature: Up to 221°F (105°C)

SCP Self-Priming Pumps

SCP series pumps are End suction self -priming Pumps and designed for pumping water, waste water and light slurry liquids. The pumps are End suction Self priming Pumps with horizontally mounted & back pull-out design. The Pumps are supplied in 1.5”x 1.5”, 2”x 2”, 3”x 3” sizes with NPT threaded connections.

Features

Rotech SCP series Pumps close coupled self-priming centrifugal pump can be mounted with NEMA C face electric motor frames (56C, 145TC, 182TC etc.), IEC electric motors and Hydraulic Motors.
SCP series are capable of lifting liquid up to 25ft from the liquid level below ground. However, for the best performance of the pump, the pump should be installed less than 15ft above the liquid level. The flapper valve will maintain a full column liquid in the suction pipeline.
Standard features include stainless steel drive sleeve, stainless steel fasteners, renewable, renewable wear plate, and a semi-open dynamically balanced impeller. Option Include double grease-lubricated seals, stainless steel impeller and seals for all types of abrasive and/or corrosive services.
