Sub-assembly parts
- Wet end (diaphragm, reagent head, check valve, valve cap, retention plate)
Wet End Features-Value points
Wet end
- Standard Materials: PP, PVDF, 316LSS,PVC
- Leak Detection (optional) comes with a pressure gauge and a switch to monitor the diaphragm integrity.
- SS alloy hardware, corrosion resistance.
Piston and Diaphragm
- Heavy duty composite diaphragm-red position
- Double sided PTFE coated composite diaphragms maximizes chemical resistance
- High strength returning spring provide enough suction-lift power to handle high viscosity fluid.
Wet End Features
Leak Free Head
- Secure diaphragm sealing technology provides leak free service
- Secondary O-ring seal offers worry free valve sealing
- Oversized valve design, flow is routed evenly without cavitation concerns
- Retention plate ensures pressure containment (hydrostatic and creep elimination)
- Increased head bolts（8-12 pcs) ensure evenly torque on plate and reagent head to improve diaphragm sealing
Connections
- Multiple connection options: Tube(DM1-2), BSPT(DM1-6), PVC Socket(DM1-6), Flange & NPT (DM7 plastic), BSPT(DM7 316SS)
- Toolless valve
- Realize fast and easy installation and servicing
Wet End Features –Value point
Wet End Material
Drive End Features
Drive
Drive
- Non-metallic, never-seized motor coupling prevents sticking or "welding" of worm shaft to motor shaft and reduces noise
- Worm lip seal prevents condensation and ingress of contaminants
- Sealed worm bearing extends gear and motor life, reduces noise, and maximizes pump efficiency by ensuring full torque output
- Advanced worm shaft and gear design converts rotation to reciprocating motion with high efficiency and remain lower noise and temperature rise.
- Compact and lightweight gearbox saves space and easy to handle
- Fully sealed, non-vented gearbox design prevents ingress of contaminants
- Protection level: NEMA 4X level, IEC IP56 level
- Robust industrial hex-head SS hardware (Same size M6)
- Oversized bearings for long life and reliability
- Shielded bearings for better protection
Oil Lubrication
- Oil bath for normal or explosion proof areas
- Lubricates all internal moving parts to extend pump life
- Visible and accessible oil fill location and oil drain location(yellow box)
- Oil sight glass for fast inspection of oil and operation (red box)
Pump and mounting feet
- Epoxy resin coating，corrosion resistance (PU coating is optional)
- Flat and solid uniform mounting feet - extend outside of the gearbox for stability
- Oversized and slotted mounting holes allow to adjust location or change base bolts
- Stable installation
Drive End Features-Value point
Stroke Control
- 10:1 turndown ratio
- Adjustment accuracy 1%
- Large font，easy to read
- 0-100% stroke range in one complete circle
Auto-lock Stroke
- Auto-lock stroke design: pressed to unlock and rotate.
- Drift free: maintain stable flow
- Oversized knob: easy to operate
- Clear rotation direction and operation instruction
Drive Connection - Lip Seal
- Lip seal design for all GLM models;
- Compared with below seal, lip seal has many advantage: less sealing part, more stable structure, longer service time;
- Easier for maintenance
- Leakage free for the drive end
Optional Configuration
New PVC Reagent Head Option - for sodium hypochlorite dosing
- Similar connection design with Pulsa & Pulsa R
- Widely used in the transport of sodium hypochlorite and sodium acetate with excellent performance
- DM7 PVC offering with PP Reagent head+ PVC check valve guide
Manual Bleed Valve Optional-Offer with PVC wet end
- Bleed valve configuration is available for all GLM models, applies for dosing vaporizable liquid such as sodium hypochlorite, hydrogen peroxide;
- Standard port to port dimension, easy for installation and operation.
- Can manually operate in pump using or stop status, quickly bleed the air;
- Material: PVC
Pulsa SPC2.0 (Smart Pump Controller)
- Brushless DC motor, higher efficiency, longer service life
- Control signal 4-20mA/0-10V/RS485 input
- 1.5RPM speed control, accuracy up to 0.1%
- Provide local and remote operation model
- Large and color screen to display flow/percentage/speed
- Applicable on integrated control panel
- High accuracy can provide massive chemical savings for the end user
GLM -IEC80 Kit (Optional)
IEC80 B14 Frame Adapter for 0.75KW Motor
- Motor for DM4-DM6 is normally configured with 0.75kw, IEC71-B14, If your customers required other brands or ex-proof motor, you could need the Kit.
GLM Design for Maintenance
Easy Inspection Design

- Multiple KOP kit service options: Lite, Standard
- Worm shaft and gear condition can be inspected through oil fill and drain connections
- Oil sight glass for fast inspection of oil and operation
- Common hardware(M6), no special tools required
Model Selection
Pump Model Configuration
For example: DM2A, normal motor, wet end material PVDF, tube connection, no leak detection, completed model is DM2A3FT, if with LD, should be DM2A3FT-L
eg: DM7C3AP, DM7 316SS, it is P, but actually the connection is FBSPT, not FNPT
