PUMP INSTALLATION
R & RX Series pumps have been evaluated for use with water or water based solutions.
Please contact the manufacturer for additional information.
Risk of electric shock. Pump models; R100, R250, R400,
R400D, R400P, R750 & RX750 (115v) are supplied with a grounding conductor and
grounding-type attachment plug. Pump models; R1500, R15, R08, RX08SS & RX15SS
do not come with electric plug connectors. To reduce the risk of electric shock, be
certain that it is connected only to a properly grounded, grounding-type receptacle.
Lifting:
Attach a rope or lifting chain (not included) to the handle (or lifting rings) on the top of
the pump.
Do not lift the pump by the power cable or discharge hose/piping.
Proper lifting equipment (rope/chain) must be used.
POSITIONING THE PUMP
BJM Pumps
, R & RX Series pumps are designed to operate fully or partially
submerged. Avoid running the pump dry for extended periods of time. Refer to data
sheet for minimum submersion depth for your particular model. Data sheets can be
obtained online at
www.bjmpumps.com or by calling BJM Pumps, LLC at 860-399-5937.
As a general rule, R and RX Series top discharge pumps can pump down to a level
above the suction screen. Pumping lower than screen will permit air to enter the pump
and cavitate, lose prime or become air bound.

Do not run pump dry.

Pump liquid should not exceed a maximum temperature of 104°F.

Never place the pump on loose or soft ground. The pump may sink, preventing
water from reaching the impeller. Place on a solid surface or suspend the pump
with a lifting rope/chain. The R & RX Series pumps are provided with a suction
strainer to prevent large solids from clogging the impeller. Any spherical solids
which pass through the strainer should pass through the pump.

For maximum pumping capacity, use the proper size non-collapsible hose or rigid
piping. A check valve may be installed after the discharge to prevent back flow
when the pump is shut off.
