Page 8: Cm Series Pump Overview
CM Series Pump Overview The CM series pump is capable of operating in 2 modes. The 2-stage design allows you to operate the pump in pressure or volume mode. An electric or manual panel-mounted controller operates the transfer valve in the pump that directs the flow to operate the pump in either mode. The pump is available with many intake and discharge options. - Page 9 Notes...

High Pressure Hazard: Changing the TRANSFER VALVE position of the transfer valve with the pump operating may result in a significant change in discharge pressure. -
Page 18: Pumping From The On-Board Tank
Safety Introduction Product Overview Operation Maintenance Pumping from the On-Board Tank the pump has a manually operated transfer valve, slow engine speed to reduce the discharge pressure to 75 psi (5.2 bar) or less. With the electric transfer valve, reducing the discharge pressure is necessary only if it exceeds 250 psi (17.3 bar). -
Page 19: Pumping From Hydrant Or Relay
Safety Introduction Product Overview Operation Maintenance Pumping from Hydrant or Relay is required (more than 200 psi, 13.8 bar), operating the pump in the pressure position may be necessary even if it means closing one or more valves to reduce volume and avoid cavitation. The transfer valve may be changed from one position to the other while operating the pump. -
