SKF MOD-031-NC Oil Reservoir
The SKF MOD-031-NC is a 3.5 litre polyethylene oil reservoir that feeds SKF VectoLub minimum quantity lubrication (MQL) systems. It supplies oil from its outlet to the VectoLub pneumatic micropump modules, specifically the VTEC and VE1B series. The reservoir holds and supplies oil only; the micropump modules set the dosing. The NC suffix marks the version fitted with the contact-type oil level switch.

What the NC Level Switch Means
The NC suffix marks the version fitted with a contact-type oil level switch for low-level monitoring. The switch circuit rating is maximum 250 V, 50/60 Hz, 10 VA, 0.25 A, with IP65 protection when the connector is fitted. Confirm the contact opening behavior against the machine control schematic before wiring.
3.3 Litre or 3.5 Litre
One SKF document describes a 3.3 litre PA6 (polyamide) tank for this designation. The catalog table for MOD-031-NC lists 3.5 litre PE. This page follows the catalog table: 3.5 litre PE, and flags the 3.3 litre PA6 figure as a documentation variance to confirm at order.
Role in a VectoLub MQL System
The reservoir feeds SKF VectoLub MQL systems with VTEC and VE1B micropump modules. The modules set the micro-dose volume; the reservoir has no metering function and only holds and supplies oil. For oil and air distribution lines, see oil-air mixing valves for oil and air distribution lines.
Mounting and Installation
The reservoir mounts using four 7 mm diameter holes. It is supplied with 3 m of 6 mm tubing, quick-connectors, and mounting screws. Position the reservoir relative to the micropump modules so the oil supply line remains short and supported. For system context, see reservoirs and oil supply within centralized lubrication systems. For a different SKF pump format, see the SKF single-line MKU11 pump as a different SKF lubrication pump format. Contact us for a quote.
Frequently Asked Questions
What is the SKF MOD-031-NC?
It is a 3.5 litre polyethylene oil reservoir for SKF VectoLub MQL systems. It supplies oil to VTEC and VE1B micropump modules.
What does the NC suffix mean?
NC marks the version fitted with a contact-type oil level switch. The switch monitors low oil level and sends a signal.
What is the reservoir capacity?
The useful capacity is 3.5 litre. This follows the catalog table for the MOD-031-NC designation.
What material is the reservoir body?
The body material is polyethylene, abbreviated PE. One older document lists PA6, but this page follows PE.
What is the operating temperature range?
The operating temperature range is -10 to +60 °C. Keep the reservoir within this range during use.
What is the level switch rating?
The switch circuit rating is maximum 250 V, 50/60 Hz, 10 VA, 0.25 A. Protection is IP65 with the connector fitted.
Is the reservoir 3.3 litre or 3.5 litre?
This page follows the catalog table and lists 3.5 litre PE. The 3.3 litre PA6 figure is a documentation variance to confirm.
Does the reservoir meter oil?
No, the reservoir has no metering function. The VTEC and VE1B micropump modules set the micro-dose volume.
Does the reservoir work with grease?
No, this is an oil reservoir for MQL systems. It is not a grease pump part.
