MARCO UP8-XC 12V Self-Priming Electric Pump

Description

Self-priming electric pumps for transferring liquids up to 4 bar pressure. The pump body and connections are made of stainless steel. The main application is high-pressure spraying of aggressive liquids.

Technical Details

Fluids Allowed / Not Allowed

¹ In the case of liquids classified as aggressive, toxic, or hazardous to health, it is essential to design the system in compliance with Directive 2006/42/EC and provide adequate protection to prevent injuries in the event of accidental liquid leakage.

Always ensure that the fluid to be pumped is compatible with the pump's construction materials. MARCO S.p.A. is not responsible for any errors made by the user.

ISO 8846 Compliant Device

Ambient Conditions

TEMPERATURE: min. -10°C/14°F / max. +60°C/140°F

WARNING: The indicated temperature ranges are applicable to all components of the pump. These limits must be respected to avoid damage or malfunctioning.

Operating Cycle

The pump can operate on a continuous cycle under the following conditions:

• Pressures not exceeding 50% of the maximum pressure indicated in the technical data.
• Temperature of the motor below 60°C/140°F or 70°C/158°F.

It is possible to operate at higher pressures/ampere draw if On/Off cycles are used, allowing the motor to cool down. Long pipelines, reduced diameters, bottlenecks, and dispensing guns can affect operating pressure. In these cases, verify that pressure and electrical draw do not exceed the values shown in the diagrams.

Transportation and Handling

Due to its limited weight and dimensions, the pump does not require special handling or lifting equipment. When handling manually, wear normal personal protective gear (e.g., safety shoes with toe piece). The pump is carefully packed prior to shipment. Upon receiving, inspect packaging for damages and store the pump in a dry area at a temperature between -30°C/-22°F and +70°C/158°F.

Installation

It is recommended that the pump's use complies with normative safety standards and the precautions listed below.

Preliminary Checks

Check for damage during transportation or storage. Clean inlet and outlet ports, removing dust or packaging material. Verify that the available electrical power supply matches the specification requirements.

Positioning

The pump can be mounted in any position. Fix the pump using suitable diameter screws corresponding to the holes. To ensure correct directional flow (indicated by the arrow on the top plate), connect the positive pole (+) of the battery supply to the red wire on the motor end-cap and the negative pole (-) to the black wire. Electrical connections must be made using adequate terminal blocks and connectors, ensuring a tight fitment of electrical cables. Improper wiring can cause power losses and/or overheating of the cabling.

WARNING: It is the responsibility of the installation technician to ensure a correctly designed circuit installation fitted according to regulations. Environmental risks must be taken into account during installation.

Tubing Connections

• Prior to making any tube/hose connections, check that the inlet ports have no end caps.
• Do not position the pump at an excessive height relative to the minimum fluid level. Damage may occur if this height is exceeded, as the pump may not draw fluid. Ensure the outlet tube is empty and without restrictions.
• Avoid restricting the inlet or outlet tubes to optimize efficiency.
• The use of an inlet filter is recommended, especially with fluids containing impurities (mesh ASTM no. 35). Frequent cleaning and maintenance of the filter is advisable. The standard filter withstands a maximum positive pressure of 0.5 bar.
• Utilize tubes and connection pieces that are resistant to the fluid types handled and avoid any possible environmental dispersion.

Electrical Connection

WARNING: DUE TO THE EMI FILTER, THE PUMP IS NOT SUITABLE FOR SWITCHING APPLICATIONS (PWM DRIVER).

The electrical installation of the pump must include a protection fuse suitably rated as indicated on the motor label.

WARRANTY EXPIRES IF NO FUSE IS UTILIZED.

Always mount the anti-vibration rubber fittings supplied with the pump kit. Their use ensures a consistent reduction in noise and vibration levels. Electrical cabling size should depend on the distance between the pump and the battery/power supply (refer to Motor Data Table). The use of undersized cabling can cause overheating of the electrical wiring and a subsequent fire hazard. There will also be a voltage drop at the motor terminals, reducing efficiency. The flow rate value indicated on the motor label is obtained with the internal tube diameter specified in the Pump Data Table. Tubes with smaller diameters will cause an increase in current, with a potential risk of motor overheating.

Troubleshooting

Check Points If The Pump Has Stopped Or Will Not Start

• Check the effectiveness of the battery power supply (voltage activity).
• Check if the fuse has blown.
• Check for foreign matter in the pump body: disconnect the power supply, unscrew the four fixing screws, remove the front cover plate, and inspect the chamber. Replace the cover plate in its original position after inspection.
• Avoid running the pump dry for more than a few minutes. Pumps found defective that have run dry without fluid are not covered by warranty.
• The average life span of the motor commutator brushes is approximately 2500 hours under normal operating conditions. Stoppages may occur due to brush wear and tear after this period.

Why The Pump Will Not Prime Itself?

• The pump is fitted at an excessive height above the fluid level.
• The pump has run dry for too long a period.
• Long periods of inactivity. In this case, add liquid directly into the chamber before start-up.
• Air leak at the suction pipe due to possible cuts in the pipe, inadequate hose clamps, or filter malfunctioning (defective/worn seals or clogged filter).
• Air leak at the front plate cover due to loose fixing screws or poor effectiveness of the seal.
• Faulty electrical cable connections.
• Presence of obstructions or restrictions in the suction or delivery pipes, or the use of special devices (e.g., automatic spray pistol or Aquastop).
• Presence of liquid loops in the outlet tube.

Good Practices Ensuring A Well Functioning Pump

If the pump will not be used for at least 30 days, especially with water, it is advisable to run fresh water through it and then loosen the front plate screws. Upon re-use, run the pump briefly (a few seconds) and tighten the screws again. Check the motor current value under maximum operating pressure against the motor label specifications.

Normal Maintenance

• Check frequently and keep the inlet filter clean.
• Check the chamber every month and keep it clean from any foreign matter.
• Check every month that the electrical wiring is in good condition.

Indicators That The Pump Is Functioning Correctly

• Temperature of body and motor frame is within 60°C/140°F and 70°C/158°F.
• Regular flow and constant noise levels.
• Amp-draw within the limits indicated in the diagrams.

To Open The Pump

It is recommended that a specialized service technician be consulted for any repair work or the replacement of worn-out internal components, exclusively with original spare parts. During the warranty period, only authorized MARCO S.p.A. personnel should perform this, otherwise the warranty will expire.

Environmental Disposal

It is the responsibility of the owner to dispose of this product via specific refuse collection structures indicated by the government or local governing authorities.

Packaging Environmental Disposal

The user is invited to effect proper waste separation to facilitate the recycling of the materials of which the packing is composed.
