Spray from leaks, ruptured components can splash fluid in eyes or on skin and cause serious injury.

Leaks from ruptured components • • • • • •

• Shut off the pump and depressurize before performing any maintenance.

• Do not tamper with or perform unspecified alteration of the device.

• Use only pipes, hoses and hose fittings rated for maximum rated pressure of the pump or the

pressure at which the pressure relief valve is set at.

• Always wear protective clothing, face shield, safety glasses and gloves when working on or

near the metering pump.

• Additional precautions should be taken depending on the solution being pumped. Refer to

SDS precautions from your solution supplier.

with the air in mechanical diaphragm pump.

SOUND HAZARD

The sound pressure level of the pump may exceed 80dBA in some pumps.

Observe all safety precautions when operating the pump within close proximity for extended

tinnitus, tiredness, stress, and other effects such as loss of balance and awareness.

MECHANICAL HAZARD

The pump may shake or vibrate during operation.

Vibration could occur due to loose mechanical component and foundation bolts, causing

•

• Do not pump non recommended flammable or explosive fluids.

• Static electricity may generate by fluid moving through pipes and hoses. A static spark could

be produced by high fluid flow rates. Grounding of the pump is a must.

• Provide fresh air ventilation to avoid the possible buildup of flammable fumes from the

process chemicals.

• Keep the pump area free of debris, including cleaning agent, rags, and any flammable material.

• Follow the cleaning agent and other cleaning recommendations as mentioned in the operation

and instruction manuals.

• Use cleaning agent with the highest possible flash point to clean the pump parts if needed.

• If there is any static sparking while using the equipment, stop operation at once. Identify and

swallowed, or inhaled.

•

• Store hazardous fluid in an approved container. Dispose of hazardous fluid according to all

local, state and national guidelines.

• Wear the appropriate protective clothing, gloves, eyewear and respirator.

• Pipe and dispose of the exhaust air safely. If diaphragm fails, the fluid may be exhausted along

•

periods by wearing hearing protectors.

• Extended exposure to elevated sound levels will result in permanent loss of hearing acuteness,

•

piping rupture and leakage of chemical to cause bodily injury. The pump should be bolted
down to the base during operation.

• Pump may overturn when being transported if the motor is too heavy. Secure the pump on its

base before transportation.

SECTION I

GENERAL DESCRIPTION

The Neptune MP7000 Mechanical Diaphragm metering pump is a reliable metering pump of the low-pressure diaphragm
type. Under constant conditions of temperature, pressure, and capacity setting, a +/- 2% metered discharge volume is
maintained. Rugged contoured composite diaphragm designed for high metering accuracy over a full 10:1 turndown
range.

A reciprocating rod at a set stroke length and rate actuates a flexible, chemically inert, Teflon faced diaphragm creating
the pumping action. Screwing in and out a hand knob regulates the capacity of the pump. Screwing in shortens the stroke
length reducing the volume and screwing out increases capacity. A percentage of flow is read on the hand knob.

Precision-engineered liquid ends meters mild solutions, aggressive chemicals, high viscosity polymers (up to 200cP) and
slurries (hydrated lime slurries up to 4 lb/gallon of water, activated carbon slurries up to 1 lb/gallon of water). If metering of
liquids with higher viscosity is required please contact factory
Metering accuracy is maintained by the ball check valves in the suction and discharge pump heads. Screw-in cartridge
ball check valves eases maintenance.

Temperature limitations on the plastic heads are: 36 – 125°F (2 - 52°C) for PVC; 36 - 200°F (2-93°C) for PVDF.

PLEASE READ INSTRUCTION MANUAL COMPLETELY BEFORE INSTALLING PUMP.
