1 Precautions
The following precautions should be taken when operating
metering pumps. Please read all sections carefully prior to
installation.
Protective Clothing
Wear protective clothing, face shield, safety glasses
and gloves when operate or near your metering pump.
Additional precautions should be taken depending on the
pumped solution. Please refer to MSDS precautions from
your solution supplier.
Water Test
All metering pumps are tested with water before
delivered from the factory. If your solution is not compatible
with water, disassemble the pump head assembly.
Thoroughly dry the pump head, check valves, seal rings,
valve balls and the diaphragm. Reassemble head
assembly and tighten the screws. Refill the pump head with
the solution before start the pump.
Tubing Connections
Inlet and outlet tubing size must not be reduced. Make
certain that all tubing is securely attached to fittings before
start-up. Always use the supplied tubing with your pump, as
the tubing is specifically designed for use with the pump
fittings. It is recommended that all tubing be shielded to
prevent possible injury in case of rupture or accidental
2
damage. If tubing is exposed to sunlight, black UV resistant
tubing should be installed. Check tubing frequently for
cracks and replace as necessary.
Plumbing Code
Please adhere to your local plumbing codes and
requirements. Be sure installation does not constitute a
cross connection. Check local plumbing codes for
guidelines. Our company is not responsible for improper
installations.
Back Pressure/Anti-Syphon Valve
If it is pumping downhill or into low or no system
pressure, a back pressure/anti- syphon valve should be
installed. Contact your local distributor for further
information.
Electrical Connections
Warning ：To prevent the risk of electrical shock, the
metering pump must be plugged into a grounded power
with ratings conforming to the data plate on the pump. All
wiring must confirm to local electrical codes. If the pump
power cable fails, change it by the factory, distributor or
authorized repair shop, in case cause any injury.
Warning：To prevent the risk of electrical shock, install on a
circuit protected by a ground-fault circuit-interrupter.
3
Tubing Depressure
All tubings should be depressured when
disassembling or maintenance, in order to prevent solution
from splashing.
Over-pressure Protect
Suggest install safety/pressure relief valve, to prevent
over pressure causing the pump or system damage.
2 Product Introduction
2.1 Overview
JLM-S metering pump is a microprocessor controlled
solenoid diaphragm pump with changeable frequency. It is
capable for all kinds of solutions dosing, including corrosive
solutions. It is widely used in petroleum, chemical, food,
pharmaceutical, paper, light industry, agriculture, water
conservancy and other industrial and technological sectors,
in the process solution metering and dosing.
Solenoid metering pump is the use of electromagnetic
push rod driven diaphragm in the pump head reciprocating
movement, causing the pump head chamber volume and
pressure changes. Changes in pressure caused by suction
4
valve and discharge valve opening and closing, to achieve
quantitative liquid suction and discharge.
JLM-S solenoid metering pump rated flow range is 1 ~
20 l / h, with corresponding maximum output pressure of 10
~ 1bar. The pump outlet displacement can be adjusted
according to the pulse frequency selection switch. It is a
simple structure, low energy consumption, accurate
measurement, with a new screen display of
electromagnetic diaphragm metering pump.
